About
A cliffside castle museum built by an eccentric inventor, filled with medieval architecture, Renaissance art, and oddball tech. Kids can explore winding staircases, secret doors, and rooms packed with armor and gadgets. Admission is $20–25 for adults, $10 for kids 5–12, and free for under 5. Open April through December. Best for ages 7+ who like weird history and don’t mind stairs... this one’s not stroller-friendly.
