DON’T FORGET... Join The O all month to lose yourself in a world of illusion and mystery. Behind one of our many hidden doors lies a limited-time Halloween pop-up exhibit, cloaked in spooky animatronic characters and curiosities. The rest? That’s for you to uncover — if you’re brave enough to roam our exhibits and haunted gardens.
Join us for our Halloween Nights Fun and celebrate the BOO season on this zany journey around the museum. Come in costume and have a spooktacular time exploring our 100 room Museum - decorated special for Halloween.
