Have you ever walked by a building and thought “I wonder what that looks like inside?” Maybe it’s the old-school brewery in your neighborhood or that new, glitzy high-rise downtown. Well, now’s your chance to take a peek behind closed doors. This month, Open House Chicago — the city’s free, public architecture festival — returns with in-person site visits on Oct. 15 and 16.

During this weekend event, you’ll have the opportunity to explore more than 150 unique sites across 20 Chicago neighborhoods, including historic landmarks, architectural marvels, and soaring skyscrapers, some of which are rarely open to the public. Here are 10 unique and interesting sites to get you started this year.

The sleek bell tower at St. Paul & The Redeemer Episcopal Church still houses the original church bell, which was salvaged from the ashes. Guests can explore the main sanctuary and enjoy live music performances both days.

Open House is the perfect chance to step inside Chicago’s most famous (and only!) castle. The Givins Castle was built in the Beverly neighborhood in 1887 as a lavish private residence for Robert C. Givins, inspired by an Irish estate he once visited. The castle, which has only ever had five owners, is now home to the Beverly Unitarian Church. Visitors can explore the ornate building — constructed out of solid limestone mined in nearby Joliet — to get a sense of what it might have been like to live like 19th century “royalty.”

Saturday, Oct. 15: 10 a.m. – 5 p.m.
Sunday, Oct. 16: Closed

Tip: Stop by Wild Blossom Meadery & Winery (another Open House Chicago site) to sample their sustainable beverages made with honey harvested from their own bees.
