The first mention of the Dorfners' Tenement House (Kamienica Nowy Świat 66) appeared in documents in 1770. Earlier there was a manor house belonging to the Dominican order. In the mid-19th century an annex in the southern part of the building was removed, but in 1897 the building was extended by several new ones. Destroyed during the war (only the eighteenth-century cellars survived), it was rebuilt in 1947-1949, with reference to its pre-war appearance. Today it houses the Teatro Hotel****
