Houska Castle

Houska Castle stands in a remote stretch of forested hills about 47 kilometres north of Prague, near the tiny village of Blatce in Central Bohemia. Unlike almost every other medieval castle in the region, it was not built to command a river crossing, protect a trade route, or project power over a town. Its setting is deliberately isolated — deep in the woods, far from any obvious strategic point — and this strangeness is precisely what has made it one of the most discussed and visited Gothic fortresses in the Czech Republic. The castle is small, exceptionally well preserved, and privately owned, which gives it an intimacy absent from larger state-managed monuments.

Construction is dated to around 1270 and is attributed to King Přemysl Otakar II, one of the most powerful Bohemian rulers of the medieval period. What sets Houska apart from every contemporary fortress is its peculiar design: there is no water source inside the walls, the defensive fortifications face inward rather than outward, and the original structure had no inhabitants, no garrison quarters, and no economic function. Historians have concluded that the building was erected not to keep attackers out, but to seal something in. Beneath the castle lies a deep natural pit in the bedrock, and the chapel was constructed directly above it — the most sacred space placed over the most feared one.

The chapel at Houska contains some of the most unusual fresco paintings in Bohemia. Dating from the late 13th or early 14th century, they depict a mixture of Christian and demonic imagery that is difficult to categorise. The most striking is a half-human, half-animal archer on the north wall — a figure that does not correspond to any standard hagiographic or allegorical programme known from other Czech churches of the period. Art historians have debated its meaning for decades without reaching consensus. The pit beneath the chapel entered local legend as the "Gateway to Hell," a portal through which demons were said to emerge, and the castle was supposedly built specifically to close and consecrate it. During World War II, the castle was briefly occupied by the SS, and various accounts allege that unexplained experiments or occult research was conducted there, though documentary evidence for these specific claims remains thin.

For visitors, Houska offers something genuinely rare: a Gothic castle that feels unaltered and slightly unsettling. The interiors are fully furnished and the guided tour covers the chapel frescoes, the legendary pit, the great hall, and the rooms used during the WWII occupation. The castle opens only on weekends in spring and autumn, and more regularly through summer, so checking the official website before travelling is essential. The surrounding forest is pleasant for a short walk before or after the tour, and combining the visit with Bezděz Castle some 30 kilometres to the east makes for an efficient full-day itinerary from Prague.
