The building was luxuriously decorated. The walls of the original building had marble revetments, while its floors were paved with tiles of white and green marble. The paving design was formed by the repetition of a geometric motif which covered its entire floor surface. The later hall had a mosaic floor and the upper part of its north wall carried a wall mosaic, parts of which were found and conserved during excavation of the site in the 1970s, as well as during recent excavations (2011-2012). This is an important find which documents the building’s importance; simultaneously it is unique because very few wall mosaics from secular buildings of this period have survived down to the present.
