Overview
Five Flags Center is a multipurpose entertainment and events complex in downtown Dubuque, Iowa. Its facilities combine the historic Great Five Flags Theater with a later arena built as part of a broader civic effort to preserve and reuse the theater site. The complex hosts concerts, theatrical productions, ballet, sports, graduations, community gatherings, and other public events. The name refers to the five national or imperial flags associated with Dubuque's history: the Royal French flag, the Royal Spanish flag, the Union Jack during a brief interruption of Spanish rule, the flag of the French Republic, and the flag of the United States. This historical reference gives the venue a civic identity rather than that of a conventional commercial entertainment brand. The theater site's history reaches back to the nineteenth century. An Athenaeum Theater was built there in 1840 and became the City Hotel, which also contained a theater, in 1846 before later being known as the Peosta House. A subsequent theater structure, built in the nineteenth century, was destroyed by fire in 1910. Local businessman Harker Brentnal Spensley Sr. and C. H. Eighmey had acquired and renovated the earlier building shortly before the fire. The present historic theater was constructed in 1910 as the Majestic Theater. Designed by George L. Rapp, it used a Renaissance Revival style with French influences. The building became a movie house in 1920, was renamed the Spensley Theater in 1929, and later operated as the RKO Orpheum. After years of decline, it faced demolition during Dubuque's urban-renewal period in 1969. A citizens' committee organized a preservation campaign, and the theater was incorporated into the Five Flags Center project in 1972. Restoration began in 1975, and the theater reopened in 1976 as the Five Flags Theater. The arena component was conceived as part of the same rehabilitation initiative. Construction began in 1976, and the arena opened in 1979, with Bob Hope performing at the first event. It can accommodate as many as approximately 5,200 spectators for basketball, while its former ice-hockey configuration provided roughly 2,500 seats. The layout includes permanent seating on one side and bleachers on the remaining sides, allowing the venue to be adapted for sporting events, concerts, and civic functions. For many years Five Flags Center served as Dubuque's principal convention and event venue. The opening of the Grand River Event Center in 2003 shifted some convention activity elsewhere. SMG assumed arena operations from the City of Dubuque in 2004, and summer renovations in 2005 upgraded concessions, entrances, and concourse areas. The complex also has a significant sports history. It hosted the Dubuque Fighting Saints of the United States Hockey League from 1980 through 2001 and the Dubuque Thunderbirds of the Central States Hockey League from 2001 through 2010. After the Mystique Ice Center opened in 2010, Dubuque's hockey activity moved to that dedicated facility. The Five Flags Theater continues to be associated with the Dubuque Symphony Orchestra, school musicals, concerts, ballet, and other performing-arts programming. In 2024, the Iowa Power began discussions to use the arena for indoor football, with play projected to begin there in 2025.
History
Five Flags Center developed from a long sequence of theater and civic-entertainment uses at a downtown Dubuque site. The first known theater on the property was the Athenaeum Theater, constructed in 1840. In 1846 it became the City Hotel, which retained a theater function, and it was later associated with the name Peosta House. A later theater building was erected in the nineteenth century, with sources identifying its construction as occurring in either 1864 or 1877. The building was acquired and renovated in 1909–1910 by local businessman Harker Brentnal Spensley Sr. and his partner, C. H. Eighmey, but it was destroyed by fire in 1910. The current historic theater was then built as the Majestic Theater. Architect George L. Rapp designed the building in a Renaissance Revival style incorporating French influences. Rapp later became widely known for his theater architecture. The theater was converted to a movie house in 1920 and renamed the Spensley Theater in 1929. It subsequently operated as the RKO Orpheum. Over time the building deteriorated, and during Dubuque's urban-renewal activity it was threatened with demolition in 1969. Local preservation advocates formed a committee and launched a fundraising drive to save it. Their work became part of the Five Flags Center project, incorporated in 1972. Restoration began in 1975, and the theater reopened in 1976 under the Five Flags Theater name. The name Five Flags refers to the flags connected with Dubuque's historical sovereignty and administration: France, Spain, Great Britain during a brief interruption of Spanish rule, the French Republic, and the United States. The restored theater became a venue for orchestral performances, school musicals, concerts, ballet, and other stage productions. A new arena was planned as another element of the theater-rehabilitation project. Construction started in 1976, and the arena opened in 1979. Bob Hope performed at the first event. The arena's design provides a flexible configuration, with permanent seating along one side and bleachers on the other sides. Capacity can reach approximately 5,200 for basketball, while the former ice-hockey setup accommodated about 2,500 spectators. Five Flags Center became an important general-purpose venue for Dubuque, serving as a convention center as well as a home for entertainment and sports. The Grand River Event Center, opened in 2003, took over part of the city's convention business. In 2004, SMG assumed operational responsibility for the arena from the City of Dubuque. Renovations during the summer of 2005 improved the concession areas, entrances, and concourses. The arena's sports history includes the Dubuque Fighting Saints of the United States Hockey League, who used the facility from 1980 to 2001, and the Dubuque Thunderbirds of the Central States Hockey League, who played there from 2001 to 2010. When the Mystique Ice Center opened in 2010, Dubuque's principal ice-hockey activity moved to that purpose-built facility. Five Flags Center remains oriented toward mixed programming, including concerts, theater, graduations, civic events, and selected sporting events. In 2024, the Iowa Power entered negotiations to use the arena for indoor football beginning in 2025.
