The oldest residential tower of Naumburg was built probably in the mid-12th century at the cathedral precincts, at the curia episcopalis, Domplatz 1. It exhibits the same dimensions as the residential tower of the Haus zur Hohen Lilie and has two Romanesque floors. Another residential tower used to be located on the south side of the west choir of Naumburg Cathedral. It had to give way to the new west choir built in the second quarter of the 13th century. The Haus zur Hohen Lilie (Markt 19) is a Romanesque secular building including a tower visible from the market square, the kitchen building to the west of the tower, the northern building bordering the tower and the Baroque building north of the northern building.
