Harder Hall, National Register historic building in Sebring, United States

Harder Hall is a former hotel on Little Lake Jackson at 3300 Golfview Drive in Sebring, designed by Palm Beach architect William Manly King in the Spanish Colonial Revival style. The 630-foot-long building held 200 rooms, a mezzanine lobby and a 4,200-square-foot great room with 22-foot ceilings and French doors facing the lake.

Vincent S. Hall and Lewis Harder began building the resort in 1925 as part of the Biltmore chain, but went bankrupt in 1927 before it opened. A group including Congressman Edgar Raymond Kiess bought it, and the Spanish Colonial Revival hotel opened on 21 January 1928. It closed in 1986 and was listed on the National Register of Historic Places on 20 June 1990.

The building reflects the architectural tastes that shaped Sebring in the 1920s when wealthy visitors discovered the town as a winter destination. The decorated tiles and curved archways show the style preferences that appealed to visitors during that era.

Harder Hall stands at 3300 Golfview Drive on the shore of Little Lake Jackson in Sebring, Florida. The former hotel has been closed since 1986 and is a private building awaiting renovation, so it is seen from the street and the lakefront rather than entered. Its 630-foot facade faces the water.

Harder Hall was the unofficial headquarters of the 12 Hours of Sebring race, hosting pre- and post-race parties and award banquets. Drivers such as Steve McQueen, Paul Newman and Mario Andretti stayed there, and in 1984 Hurley Haywood said he still stayed at "pink old Harder Hall".
