Berchembogen, Gothic Revival château in Trstěnice u Mariánských Lázní, Czech Republic

Berchembogen is a two-storey Gothic Revival hunting lodge with an irregular ground plan, entered beneath an ornate balcony flanked by corner risalits and bay windows. Two saddle roofs with gables cover the building, and the front gable carries the builder's coat of arms. Inside, a corridor with a net vault leads to rooms with carved ceilings.

Jan Arnošt Berchem-Haimhausen had the lodge built on his Chodová Planá estate for rest during hunts. The project was drawn up in the 1870s, completion was planned for 1875, but the building was finished in 1876. The family used it until the 1940s; after 1945 it was confiscated and served the state forests until the early 1990s.

The lodge's name comes from the Berchem-Haimhausen family, who used it for rest during hunts until the 1940s. After 1945 the Czechoslovak state confiscated it and the national enterprise Státní lesy took it over; in the early 1990s it was converted into a restaurant.

The château is located in forest terrain outside Trstěnice and is best reached by private vehicle, as public transit options are limited in this rural area. The nearby town of Mariánské Lázně offers better connections for visitors traveling from farther away.

The lodge was planned for completion in 1875, but construction ran late and it was finished in 1876. Its design is linked to plans for the castles Neuhaimhausen and Jalový Dvůr near Broumov, and Jan Arnošt's building activity culminated in the new château at Chodová Planá.
