Welcome to “Where is it?” Wednesday!

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted rough green stone cladding this circular building. Kellie Moreno and Ellen Martin are correct that this is the Casper Planetarium!

Completed in 1966, the Casper Planetarium was the first of its kind in Wyoming! The idea of constructing a planetarium was by the Casper Kiwanis Club cooperating with the Casper-Midwest School Board to provide a scientific laboratory for students grades 4 - 12. The project was funded by the Casper Kiwanis Club, the school board, and a federal grant. The location of the building was a gift from H.L. “Tex” English.

Designed by Casper architect, Henry Therkildsen, and built by J. Jones Co., general contractor; this MidCentury Modern building is circular in design with the dome theater located at its center while offices, restrooms, exhibits, and gift shop are located along the outer ring. The dome is 30ft in diameter and contains 58 seats (originally 70 prior to seat upgrades). The original star projector cost nearly $20,000! It has since been replaced by a digital projector that can play 360-degree fully animated graphics and films.

The Casper Planetarium is still being used today for students around Natrona County as well as providing public shows. The Casper Planetarium is not listed on the National Register of Historic Places.

“Where is it?” Wednesday will be taking a two-week break; and will return on August 19th with a new building to guess. Stay cool as you go out and admire Casper’s historic buildings!

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted a metal sliding door rail on this building’s eastern facade. Kellie Moreno is correct that this building was Milo’s Toyota Sales! Built around 1945, this small brick building served as a home to: the Natrona Agricultural Supply Co, Zeon Signs, Milo’s Toyota Sales and Body Shop, and most recently as the Flowstate office. Constructed on concrete foundations, this brick building is in utilitarian in design and function. Despite the most recent remodel and addition, several historic elements are still present at the building including: the terra cotta parapet coping tiles, double-leaf sliding wood doors, the restored “Milo’s Toyota Sales and Body Shop” ghost sign, and header brick windowsills. Milo’s Toyota Sales is not listed on the National Register of Historic Places.

Welcome to “Where is it?” Wednesday!

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted terra cotta window trim featuring a rosette. Kimberly Hershelman Brehm is correct that this is the Casper Women’s Clubhouse!

Originally called the Midwest Oil Company Hotel, this brick building was designed by local architects Garbutt and Weidner in a Georgian-style. Like other buildings designed by this firm, the clubhouse also features ornamental moldings, decorative terra cotta window trims and flower boxes. Fir, oak, and pine woods were used for interior woodwork; and ornamental iron railings for the staircase and upper balcony.

Constructed in the 1920s by the Midwest Oil Company, the building originally served as a hotel/living quarter for its male employees and guests; and was also used for social events. The hotel switched hands with Standard Oil before the building was purchased in 1939 by several women’s groups, renaming the building as Casper Women’s Clubhouse. They bought the hotel building for $8,000; about an eighth of the original cost to construct the building. For over half a century, this building served as a hub for women's social activities and humanitarian functions. These organizations included: Beta Sigma Phi Club, Daughters of the American Revolution, Casper Women’s Club, American Association of University Women, Fine Arts, and Women's Department Club. Today the building is a private residence. The Casper Women’s Clubhouse has been listed on the National Register of Historic Places since 1983.

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted one of three dormers overlooking Wolcott Street. Katie Stebbins is correct that this is the Henning Mansion at 1108 South Wolcott Street!

Located at 1108 South Wolcott Street, this Colonial Style home was completed in 1924 for Welker F. Henning, Casper’s first millionaire. Instead of making money through oil, Henning was a plumber by trade and used the first mechanical trencher to construct the storm sewers in Casper (typically work was done by hand and horse drawn construction). He also owned Hotel Henning, formerly the Midwest Hotel, once located at 1st and Center streets. The house is constructed out of blond bricks, with a course of stone running continuously between the first and second floors, and green clay tiles for the roof. Custom built inlay furniture, bathrooms for each bedroom, a library, drawing room with wall panels made of silk, sewing room, breakfast room with a kitchen featuring an electric refrigerator, electricity throughout the house, a large ballroom, and basement. The Henning Mansion has been contributing to the South Wolcott Street Historic District since 1988.

Welcome to “Where is it?” Wednesday!

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted a diamond pink granite block set into a vertical reveal for this building’s entrance. Kersty Cundy is correct that this is the Ohio Oil Company Building located at 159 N. Wolcott Street!

Completed in 1956, the Ohio Oil Co. Building was designed by Ohio architect A. G. Hall of Wilbur Watson Associates in an Art Deco architectural style. The building was constructed in two phases; an L-shaped component was completed in 1949 and then a southern component was added to create the current U-shape building footprint in 1956. The U-shape building allows natural light into the interior offices and provides additional parking space. The building’s design would allow a vertical expansion of two additional floors atop its existing four, if needed. The interior featured movable metal partitions - a standard size that had metal on both sides and filled with insulation as well as a raceway along the base for wiring - that were used to divide office spaces. The interior used Montana Rose Tan travertine, Tennessee Imperial Black, Tennessee Pink marble, and Buff Roman travertine finishes. The Ohio Oil Company originally was based in Thermopolis before moving to Casper around 1917. In 1921, it took over the Midwest Oil Company, and in 1962, changed its name to Marathon Oil. During the 1980s downturn in the energy industry, Marathon moved its Rocky Mountain regional headquarters to Cody, leaving the building vacant for a decade before Robert C. Ide purchased it in 1997 and renovated it to allow new office tenants. The Ohio Oil Co. Building has been listed on the National Register of Historic Places since 2001.

Welcome to “Where is it?” Wednesday!

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted a round concrete window sill. Katie Stebbins is correct that this is the Dean Morgan Middle School!

Located at 1440 South Elm Street, this school is the first in Casper to be specifically built as a junior high school. Designed by local architecture firm, Krusmark & Krusmark, the school is an example of the International architecture style - lacking ornamentation and instead focusing on a more industrial look with clean horizontal lines, flat roofs, bands of windows, and a low building profile. Instead of being centrally located, the entrance wraps around the corner of 15th and Elm as a little one-story projection from the original “L” shaped building.

Like Roosevelt, Dean Morgan also had a couple of strikes during construction, delaying the project and even opening the building while it was still under construction in 1953. Originally designed to have 7th, 8th, and 9th graders located in one building; the brand new building was too small to house all three grades, so only the 7th and 8th graders were having classes in the new school building. Additionally, the students had to walk to NCHS for lunch. A west wing of the building was built in 1955 that contained the cafeteria/auditorium, a kitchen, gym, locker rooms, orchestra/band room, and 11 more classrooms on the second floor. These additional classrooms did not solve the overcrowding problem until East Junior High was completed. In 1994, a new gym was added to the north of the 1955 addition. Dean Morgan Junior High School has been listed on the National Register of Historic Places since 2016.

Welcome to “Where is it?” Wednesday!

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted this building’s cornice wrapping around into an alley. Katie Stebbins is correct that this is the Hair Bar at 322 W Midwest Avenue!

Located at the corner of Midwest Avenue and Ash Street, this two-story poured concrete industrial building was built in 1922. Advertisements appeared in the The Casper Daily Tribune as early as December of 1921, boasting that the new two-story building will be fireproof and has several spaces available for rent including: a 60ft x 140ft first floor garage facing Ash Street, 5 shops or stores on the first floor, and 7 shops or offices on the second floor. Originally, there were large multi-light steel windows and storefronts placed in between each pier - however these have been replaced with smaller windows / storefronts or completely infilled. Some of the businesses that resided at this location include: Casper Sheet Metal Works, Krunf Motor Car Co., Steen & Shaull Welding, Midwest Electric Service, Shultz Walter wholesale grocery sales room and garage, Huffman’s Body Shop, North American Van Lines, the Standard Oil’s district offices, The Bracken Co., and the Plymouth Center. This building is not currently listed on the National Register of Historic Places.

Welcome to “Where is it?” Wednesday!

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted a recessed diamond pattern brickwork on this building’s south facade. Katie Stebbins is correct that this is Roosevelt High School located at 140 E. K Street!

Designed by local architecture firm Garbutt, Weidner, and Sweeney, Roosevelt School was built to serve North Casper’s student population that swelled during the oil boom. The school’s style is of a central block with wings, typical for institutional structures at the time. The main entrance is located on the east elevation where the central portion protrudes out with a porch providing a little protection. “ROOSEVELT SCHOOL” is engraved in the limestone above the second story windows. These details are reflected on the south elevation, which served as the school’s main entrance for its first two years.

Briefly called North Casper School, the school boasted 14 rooms that included 11 classrooms, showers, kitchenette, restrooms, and a cafeteria (which was unusual at the time). The south wing of the school was constructed in 1922 and was opened to students that year despite it only being half completed. In 1924, the center and north wings of the school were completed and the building finally had the promised 14 rooms. One reason why the school was halfway completed was due to a local labor strike and lack of qualified workers.

A gymnasium / auditorium was added to the north end of the school in 1959; and an addition containing the administrative and counseling offices as well as an elevator was constructed in 1995. The Roosevelt School has been listed on the National Register of Historic Places since 1997.

Welcome to “Where is it?” Wednesday!

Every week, we will be posting a picture of a historic building in Casper, and you have a week to guess which building it is.

Last week’s photo depicted brick pilasters with a stepped dark brick cap below the decorative cornice. Kellie Moreno and Katie Stebbins are both correct that this is the NIC Art Museum located at 400 East Collins Drive!

Built in 1924, this building was originally the Mountain States Power Company Power Plant before becoming the Casper Lumber Company. By the 1980s, the building was abandoned. In 1989, the building was renovated into the art museum as it is today, adding east and west wings of the building to expand its footprint for galleries, storage, and museum shop. The building’s block style emphasizes its size, especially when it was isolated between the Chicago & Northwestern Railroad and the surrounding streets. Each facade has a set of pilastered piers that creates an illusion that this building is much taller than two stories; a lintel frieze links the top of these piers to the building’s cornice. Most unusual about this building is the fact that there’s artistic detailing in its architectural elements despite its industrial function. The NIC Museum is currently not listed on the National Register of Historic Places.

This week’s photo depicts a recessed diamond pattern brickwork on this building’s south facade. Hint: this building is located in North Casper.
