House of the Black Madonna

This is genuinely the world's only Cubist museum, housed inside Josef Gočár's 1912 architectural masterpiece that pioneered Cubist building design. You'll see original Czech Cubist furniture, paintings, and decorative objects from 1911-1919, including Pavel Janák's angular chairs and Vlastislav Hofman's geometric ceramics. The collection is small but extraordinary: every piece represents a brief moment when Czech artists applied Cubist principles to everyday objects like lamps, vases, and tables.

The museum occupies just three floors of the narrow building, so you'll move through intimate rooms rather than vast galleries. The Cubist furniture looks surprisingly modern, with sharp angles and faceted surfaces that catch light dramatically. What's remarkable is seeing how artists transformed ordinary objects into geometric sculptures while keeping them functional. The building itself is part of the exhibition, with Gočár's angular facade and crystalline details visible from every window.

Most visitors rush through in 30 minutes, but you should spend at least an hour to appreciate the craftsmanship. At 150 CZK, it's excellent value for such rare pieces. Skip the basement level if you're short on time: the ground floor furniture collection is the real highlight. The museum shop sells quality reproductions, but they're expensive at 800-2000 CZK for small items.
