Armory
From U of I Wiki
The Armory is a large campus building at 505 East Armory Avenue, on the block between Armory and Gregory and between Fourth and Sixth Streets.
The Armory is home to the campus's Army Reserve Officer Training Corps, Air Force Reserve Officer Training Corps, and Naval Reserve Officer Training Corps. The floor is an athletic facility and has a lap track. There are various classrooms and offices in the Armory and room 100 is the Armory Theatre.
When construction was completed in 1914, the building was considered the largest structure in the world without a center support.
The Armory is known for being a confusing building to navigate. Expansions were made after the building was completed.
