Looking for something to do today? Agenda‘s got you covered:

The Chicago Architecture Foundation hosts its second annual open house, a two-day event where attendees can learn about notable local buildings, including the International Museum of Surgical Science in the Gold Coast, the Logan Center for the Arts in Hyde Park, and Thalia Hall in Pilsen.

Logan Square is hosting an art walk—aptly titled “Squared!”—that begins at the intersection of California and Milwaukee. Live musical performances accompany art installations and crafts from local vendors.

Put this one in the sports-you-didn’t-know-existed category: The Chicago League of Lady Arm Wrestlers will do battle at O’Malley’s Pub, with proceeds benefiting Sideshow Theatre Company and its partner charity, Rock for Kids.
