Dubuque YMCA Building, also known as the Iowa Inn, is a historic building located in Dubuque, Iowa, United States. Several area churches partnered to form the local YMCA in 1857. It was one of the first chapters formed west of the Mississippi River. Its activities ceased during the American Civil War, and it was reformed in 1866. They rented rooms on Main Street for their activities. Its first modest gymnasium was outfitted in 1884, and it was improved in 1992 when YMCA took over the facilities over the former Dubuque Athletic Club. The local YMCA completed the first section of this facility two years later, with the second section completed in 1916. Often the local YMCA chapters copied or adapted one another's building designs, which gave their facilities an institutional character in form and style. The Romanesque Revival style was popular in Iowa in the 19th century, which is reflected in the 1894 section. In the early 20th century they generally employed the Neoclassical and Commercial styles, and the 1916 wing reflects the Commercial style. YMCA remained here until 1969, when they opened a new joint facility with the YWCA on Dodge Street. This building became the Iowa Inn, which rented rooms to low-income people. MetroPlains Development of St. Paul, Minnesota bought the building in 2000 and renovated it into an apartment building for senior citizens known as the Henry Stout Apartments. It was named for an early supporter of YMCA in Dubuque.The building was listed on the National Register of Historic Places in 2002.

Upper Main Street Historic District is a nationally recognized historic district located in Dubuque, Iowa, United States. It was listed on the National Register of Historic Places in 2005. At the time of its nomination it consisted of 24 resources, which included 18 contributing buildings, and six non-contributing buildings. In 2011 the boundaries of the district were expanded to include four additional buildings on the west side of the 900 block of Main Street. The district is the northern end of the city's most important commercial street. It is situated on a level terrace above the downtown area, located to the east. The buildings located on the east side of Main Street have exposed foundations along the alley because the grade descends in that direction. For the most part the district is made up of commercial buildings, although there is one house, four rowhouses, and a church. All of the buildings are masonry construction, and they are between one and four stories tall. The bell tower of St. Luke's United Methodist Church (1896) is equivalent to an eight-story building. St. Luke's Church and the Interstate Power Company Building (1894, 1956) are individually listed on the National Register.

It was listed on the National Register of Historic Places in 2002.It was deemed important as a "national treasure". The theatre has the largest of all stages ever in Dubuque, and is Dubuque's only surviving opera house. It is architecturally important as an early Richardsonian Romanesque building in Dubuque and as a salient work of Chicago architect Willoughby James Edbrooke. It is Edbrooke's only surviving opera house, and he used its design in his design portfolio that won him the position of Supervising Architect of the U.S. Treasury Department in 1891. Its design is said to be "representative of Edbrooke's smooth exterior wall interpretation of the Richardsonian Romanesque style." It is also historically important from its association with high-quality theatre in Dubuque during 1890-1928. The theater has been preserved with great historic integrity and, in 2002, was being restored for continuing use in live stage entertainment. Its history is extremely well documented.In 2015 performance events at the theater marked its 125th anniversary.
