Have you ever driven past the Cave House in Tulsa and wondered about its story? If so, you're not alone. This quirky building has a fascinating history dating back to the 1920s when it was built as the Cave Garden Restaurant. By day, the restaurant served food on picnic tables, but at night, it transformed into a speakeasy accessed through a secret tunnel in the fireplace that led to a big room under the hill. Today, the Cave House is a museum dedicated to this piece of Tulsa's past. You can schedule a guided tour to see the meandering halls and steep staircase and learn about the exciting characters that once lived there. The current owner has decorated the interior with nods to previous occupants, including a key tree for the mysterious key woman who is said to have haunted the house. Unsurprisingly, the house has been featured on HGTV's "Home Strange Home" and in the book "Weird Oklahoma."
