The Armory, located at 3660 Market Street, St. Louis, MO was designed by St. Louis City architect Albert Osburg and completed in 1938 to house the 138th Infantry Missouri National Guard Armory. Over the decades, the building has been home to the St. Louis Tennis Club, national bowling tournaments, rock concerts, indoor sports leagues, and more. Now, the 205,000-square-foot multi-venue destination is the largest indoor entertainment spot in St. Louis.

The $60 million complex was developed by Green Street Real Estate Ventures with architecture by HDA and interiors by O’Toole Design.  Armory STL opened its doors mid-December 2022 and features nearly six acres of flexible space to gather, play, eat, drink, and discover.


Armory STL boasts a 60-foot stage to host live entertainment every weekend and monthly national and regional touring acts; 6 bars; more than 70 tap handles; over 40 interactive games; a two-story slide; dozens of TV screens; VIP event spaces; and so much more.

I have been a part of a number of large-scale venue openings and operations, and this is the one I’m most excited about.
