Stegeman Coliseum, Multi-purpose arena in Athens, Georgia, United States

Stegeman Coliseum is a 10,523-seat multi-purpose arena in Athens, Georgia, United States. Its barrel-shaped ceiling curves along the Sanford Drive side, giving the seating a U shape with a flat end that holds the scoreboard and lacks upper tiers. The roof is a separate structure linked by an aluminum bellows that lets it rise and fall with temperature changes.

Stegeman Coliseum opened in 1964 as Georgia Coliseum, replacing the 3,000-seat Woodruff Hall built in 1923. Its first game on February 22, 1964, saw Georgia upset Georgia Tech 81–68 before a record 13,200 spectators. On March 2, 1996, it was renamed for longtime coach Herman Stegeman, and it hosted rhythmic gymnastics and preliminary volleyball at the 1996 Atlanta Olympics.

The arena is named after Herman Stegeman, a longtime Georgia basketball coach who helped organize the original Southern Conference basketball tournament in 1921. Its flat end, once a stage, now holds a scoreboard, student seating and banners celebrating the Bulldogs' teams.

The Sanford Drive side is curved and decorated with Olympic insignia from the 1996 Games. The flat end holds the scoreboard and lacks upper-level seating. An adjoining practice facility for basketball and gymnastics opened in October 2006.

The roof features a remarkable structural design: a separate roof section is connected to the main building by aluminum bellows that expand and contract with temperature changes. This clever solution was innovative for its era and demonstrates early application of flexible engineering in building design.
