Hotel Forum was built in a prominent place at the Vistula River, in a short distance from the Wawel Royal Castle. The building is a kind of megastructure – 110 meters long and about 40 meters high. Its form is bent according to the shoreline of the river. The main block is raised high above the ground on several vertical service towers (concrete pillars are hidden in the structure of the towers). The construction of a hanging platform (massive reinforced concrete beams and slabs), on which other floors are set, is exposed. Written by Wojciech Niebrzydowski

Mostly vacant, future uncertain. Used as "Poland’s longest billboard", former reception area and ground floor in use by a bar and a sauna complex.
