Hus' House, Constructivist church building in Vinohrady district, Czech Republic.

Hus' House is a reinforced-concrete Hussite church complex built in constructivist style by Pavel Janák, consisting of a prayer hall, a five-storey residential block and a 34.5-metre tower. The tower's four corner pillars rise without an outer shell, and a 2.35-metre copper chalice weighing 700 kg crowns it.

The Vinohrady congregation bought the plot near the old water works in 1925 and commissioned Pavel Janák directly, without a public competition. The foundation stone was laid in 1930, construction ran from 1932 to 1933, and the first service was held on 1 October 1933. The theatre below the hall became a columbarium in 1938.

Inside, a tall statue of Christ by sculptor Jan Znoj stands prominently, alongside earthenware reliefs showing apostles and figures from the Czech Reformation. These artworks shape how visitors experience the spiritual space and connect it to local religious history.

The complex stands at the corner of Dykova and U vodárny streets by Bezručovy sady, near the Kladská primary school and the Latvian embassy. The columbarium occupies the lowered ground floor beneath the prayer hall, reached by a staircase decorated with Jaroslav Horejc's Last Judgment. The tower's spiral cast-iron staircase climbs only to mid-height; higher floors are reached by ladders.

The tower's role as a radio transmitter in May 1945 came about because broadcasting equipment had been left there in April after an organ concert; more gear was carried in secretly from Czech Radio on the night of 6 May by technician Verner and announcer Zdeněk Mančal, with help from pastor Arnošt Šimšík.
