Set in the center of Barcelona, in a 13th-century building, deep in the shadow of the Basilica de Santa Maria del Mar, Nightmare Horror Museum Barcelona invites you to come and face your fears. Try our interactive experience, set in complete darkness, with surprises along the path, as have already over a million visitors worldwide. See if you have what it takes to complete the maze or join the thousands who have chickened out (asked to stop the experience).
