The Promenade, Union Park, postcard 5

The Promenade, Union Park, postcard 4

An interesting feature of this postcard is the lack of park benches in The Waiting Area. Where have they gone? I would guess this image was taken between 1909-1910 because of the clothing style and also the cement work looks rather new. The planters also seem to be a new feature in this image.
Visitors would continue down The Promenade to get to other areas of the park including the children's playground and in later years the Mammoth Theater. This postcard was mailed in 1912.

The Promenade, Union Park, postcard 3

Take note of the fountain in front of the tree with 3 trunks that still grows today. Also, there were many planters on the grounds. The park was well-known for its beautiful flowers. The postcard in my collection was used in 1922; however, the straw hats worn by the men were typical of the 1910s.

Union Park Now: The Waiting Area
Saturday, November 14, 2009
The View from the Pavilion, Union Park

People gathered on the benches to wait for their friends and family to arrive. The young girl on the right is eating an ice cream cone. Note the straw hats for men and decorated, large hats for women that were all the rage in the early 1900s. Everyone looks so happy. Perhaps they were waiting for a dance to start.

Union Park Now: The Tree with 3 Trunks

Monday, October 26, 2009
The Pavilion, Union Park

Under magnification, you can see electric lines and hanging lights. Also, there is faint writing in pencil visible on the roof. It is difficult to decipher and I can not make out the second word. It says, " Dance _______ hall floor"
All that remains of the site today is the tree with 3 trunks on the left and the triangle garden in the center of the sidewalk. To this day purple Irises and Bleeding Hearts still bloom in the garden even though it is overgrown with weeds. It would be a great restoration project for someone interested in historical gardening. Also, the portion of sidewalk in the bottom center of the image leads to the Waiting Area.
When the park was dismantled, the fountain on the left ended up at the Ryan House in Dubuque where customers could see it first hand. However, now it may be residing at the Dubuque Arboretum. According to Encyclopedia Dubuque, the other fountain, went to the former home of Joseph A. Rhomberg.

The Recreation Grounds

There are 2 distinct styles of handwriting on this postcard. The first hand is written by the sender. The second hand is responsible for the notes on the postcard image directly. Written in pencil, the writer noted the function of the buildings. The Pavilion is labeled "dance hall". There are also notations for "ice cream hall," "pool hall," and "bowling alleys."
This image has a notation: Copyright 1906 by F.L. EGELHOF. He is the same photographer who took the black and white image of 4 trolleys posted earlier. The two images could have been taken on the same day.
It is interesting to note that there are no fountains in front of Pavilion. Also, you can still see the old style wooden electric poles; therefore, photo was probably taken between 1901 and 1904. This card was postally used in 1907.

The Promenade, Union Park, postcard 2

The sidewalk in front leads to the restrooms. At the time of this photo, there was a merry-go-round for children to play on. It was located on the lawn of the Pavilion along with large planters. You can also see the creek cutting through the lawn. The sidewalk off to the left was known as The Promenade; you can see people strolling down it. The building on the right is the Ice Cream Stand. In the background center there is a large sign advertising "Chatauqua Opens Today".
The card in my collection was not postally used. However, based on the clothing in the image I'm going to estimate that it was taken around 1910.

The cement work in this postcard looks new. I would guess this image was taken around 1910. Most of the sidewalks are still there today in fairly good condition.

Union Park Now: The Roller Coaster area


The top photo above shows the valley where the coaster once resided. It rested south of the fishpond. In fact, you can see the fishpond in the lower right-hand corner of the photo. The second photo shows the creek that runs through that same valley. It's difficult to imagine a roller coaster in this area, but it is possible if you simply picture it without all the trees and forest undergrowth. One of these days, I'll have to go searching for the cement post holes that are supposedly still there marking the site of the Dubuque's only roller coaster.

Wonder Cave, Union Park postcard 1

This postcard was used in 1909. According to Iowa Underground (2004) by Greg A. Brick, this cave was originally known as Timmen's Cave. The former lead mine was rediscovered by Greek rail layers as they put in the trolley tracks in 1900 or 1901. The cave is located on the hill south of the Loop. The entrance was bombed shut after the park closed in 1934. At the present time the cave is unstable and off-limits to visitors.

The Lodge, Union Park

Take a close look at the sidewalk leading up the hill and the little pine tree in this image. Both the sidewalk and tree still exist as you will see in the next post. The tree has grown into a giant specimen. The sidewalk is still passable and once lead park visitors up to Wonder Cave.

In the following posts you will see photos of the platform up close. Over the years I have seen it begin to crumble and erode. Every Spring the silt that builds up from melting snow and run off is removed. If it weren't removed, all evidence of the sidewalks and platform would be hidden.

The Depot, Union Park, postcard 3

This image features The Depot (a.k.a. The Waiting Station) tinted in a brick red color instead of the green we've seen previously. The plants featured in The Loop area have a different configuration. It appears that cannas were planted in the center garden that summer. Union Park was well-known for its collection of flowering plants. The groundskeeper, Mr. Bonz, kept the bulbs in the greenhouses during the Winter and replanted them in the Spring.
Saturday, August 1, 2009
The Depot, Union Park, postcard 2

The Waiting Station was created to shelter patrons from inclement weather. It also created a grand entrance area to the park. This image features a summer open-air trolley, number 95. Notice the man standing by the flowerbed in the center; possibly he is the groundkeeper Mr. Bonz or perhaps Park Manager L.D. Mathes. Who knows? Under magnification it is possible to see little bridges that divert visitors to the left and right after arriving at the park. Also, you can see a building off to the right of the Waiting Station situated on the hill. Possibly these are the restrooms. This item was postally used in 1910.

The Depot, Union Park, postcard 1

By this time the ugly electric poles have disappeared and we start to see hanging light fixtures (like the one in the center of the upper third of this postcard). From the center of the Waiting Station and veering off to the left, the sidewalk to the Fish Pond is visible. Also, the Bowling Alley and The Pavilion are visible through the Waiting Station and the trees.

The Loop, Union Park, postcard 3

This is a color postcard from an era similar to the previous post. This postcard was postally used in 1907, but again the image was most likely taken between 1900 - 1904 due to the style of the loading docks and railings. The Bowling Alley is visible in the background behind the trolley. Picnic tables are visible on the hillside to the right. Also, note the crude electric poles which will change over time. The flower beds again feature cannas. The garden in the center has changed configuration.
Sunday, July 12, 2009
The Loop, Union Park, postcard 2

Once again the Loop is featured as it appeared in the early days. Notice the 4 trolleys lined up with people boarding. The building behind the 2nd trolley appears to be the Bowling Alley. The Pavilion is just visible behind the 3rd and 4th trolley cars. Flowering cannas are often featured in the gardens. The flowers and plants pictured in the center of the loop have a very similar configuration to the next post.

The Loop, Union Park, postcard 1

Over the following series of postcards, pay attention to the flower beds inside the Loop. Notice how the beds change from year to year with the flowers and bulbs being reused in different patterns.

The Trolleys to Union Park

According to Michael M. Boge's book, Union Park: A Place of Memories, the trolley line to Union Park began at 6th and Iowa streets. The line continued out Couler on what is now Central or Highway 52 and curved into the valley to the entrance of Union Park. The trip cost 15 cents each way. I have not been able to obtain an image of the trolleys in that location. The postcard above is the closest I could find to illustrate what Dubuque looked like in that era. I'm hoping to visit Dubuque this fall for the University of Dubuque Homecoming celebration. Then I will take photos of this same image as well as the location at 6th & Iowa. The department store on the right is Willners. The sign in the top floor windows say J.W.? Law Offices. I will try to do more research to discover who the attorney was. I am also in search of newspaper articles and maps to illustrate the trolley routes. Also, the time on the clock is 11:55 (we'll assume a.m.)
Below is an approximation of the trolley line to Union Park. It is by no means accurate, but it is a start. The map is interactive and you can drag the image around to follow the blue line to Union Park.

Share Your Photos
Do you have more information or insights about Union Park? Do you possess historical family photos taken in Union Park? Would you would like to share your information and images with the world? Consider sharing them here at Union Park: Then & Now. Full credit will be given to your contribution.
I'm particularly interested in photos of the roller coaster or the fish pond as well as the interior of the Mammoth Theatre. Family photos of the dance hall or the wading pool would be a great addition as well. If you are interested in sharing, please email me.

Stewart Park
In the early days of the electric business, it was difficult to convince people to patronize the electric trolley system. Thus the Dubuque Electric Railway, Light & Power Company sought a way to showcase the service and purchased approximately 40 acres of land from the Stewart Property to create a park. The trolley line, operated by the Allen & Swiney Motor Line, was extended out to the proposed park, which was to be called Stewart Park. The only way to gain entrance to the new park was by trolley, thereby increasing patronage.
The park was named for William Graham (W.G.) Stewart, a prosperous Dubuqueland resident. W.G. Stewart settled in Dubuque in 1834 where he pursued mining, smelting, and farming. He also had many other interest that served Dubuque County well. For example, he was elected the county's first sheriff and served on the Board of Supervisors. Additionally, he was a state senator and the county treasurer. Over the years he accumulated 900 acres of land. In 1890 at the age of 77, he "donated" some of his farmland, then known as Stewart's Grove, for the proposed park. Stewart park operated from 1890 to 1900. It was known as Union Park from 1901 until it closed in 1934.

Book Review: Union Park: a place of memories
I first heard of Union Park when I was a freshman at Wahlert High School, Dubuque. The topic was part of a unit on Dubuque History in Mr. Bill Rhomberg's social studies class. Almost two decades later, my interest was re-ignited, and I was fortunate enough to come across a copy of Union Park: a place of memories written by Michael A. Boge. I found my copy in the gift shop of the Dubuque Arboretum. It was printed in 1983 and offered my first glimpse of Union Park as it used to be.
The book is 118 pages and includes 6 chapters: In The Beginning, Stewart Park, Union Park, The Flood, The Revival, and A New Beginning. The book includes a history of the park as well as a first hand account of the day of the flood as told by Arletta Mitchley. There are photo images of the aftermath of the flood. The book also includes a hand-drawn map of Union Park Hollow. While there is a bibliography, many of the images are uncredited.
The book is currently out of print; however, copies are available at a few libraries. To find out if one is available at your local library, search the Worldcat database. If your library doesn't own a copy, stop by the Reference Desk and ask about doing an Inter-library loan. To find a library near you, search the Library Locator.

Visiting Union Park
The land that once was known as Union Park now belongs to the Dubuque YMCA. It still hosts hundreds of children each summer as the YMCA Union Park Day Camp. It is private property. No trespassing is allowed.
While I have hiked the grounds many times, I have always requested and received permission first. If you are ever in the Dubuqueland area and wish to see the hollow for yourself, stop by the Dubuque Y building. Talk to the people at the Reception Desk and get permission before entering the campgrounds. You can also contact them for more information, just click here.

Union Park Map

This is my conceptualized layout of Union Park as it may have appeared at the time of the flood in 1919. Labels are coming soon. The locations of the buildings and attractions are only estimates. Expect this entry to change as future renderings will replace this original drawing. Hopefully, the map will become more accurate as I gather more information and photos.

Union Park: 90 Years Ago Today

Although the park reopened a few days later, it never quite recovered from the financial loss of that fateful day. Other factors contributing to its' demise included the popularity of automobiles and competition with another popular Dubuque attraction called Eagle Point Park (which is still in operation today).
This blog features entries with postcards and photographs of the park as it once was and as it is now. The images are arranged in the same order as they would appear if you were walking down the Union Park Promenade yourself. So take a stroll through these images and visualize a carefree yesteryear where the distractions of cell phones, leaf blowers, and lawn mowers were non-existent. Enjoy your trip!
