Berlin Species Protection Team BAT e.V.

Located inside the historic Spandau Citadel, this unique sanctuary houses around 200 tropical fruit bats year-round and serves as a winter roost for up to 10,000 hibernating European bats. Visitors can observe active bats up close in a specialized show cellar that operates on a reversed day-night cycle while learning about vital conservation efforts.

Audience reactions are mixed, with many viewers finding the sanctuary fascinating, educational, and well worth a visit. However, others express strong ethical concerns about guided tours and artificial light disturbing hibernating bats, alongside worries regarding parasites.
