Red Crayfish Pharmacy

Why visit

The house was built in the 18th century in the moat of the city fortifications, and part of it is a rebuilt medieval barbican. For generations it held the Rococo pharmacy U červeného raka, later the Museum of Pharmacy.

Since spring 2026 the Bratislava City Museum has used it as a visitor centre on the city’s defences. It is the natural first stop before climbing Michael’s Tower next door.

What to see

• Pharmacy interior: the preserved Rococo dispensary fittings and Baroque-Classicist ceiling paintings.
• City defences: how the town walls, Michael’s Tower and the barbican grew and shaped medieval Bratislava.
• 3D model: the town as it looked in the late 15th century, with an animated story.
• Tower game: an interactive game in which you piece together the building history of the tower and barbican.
