The building that lies next to the Cathedral is one of the buildings that was not destroyed by the earthquake of 1908. It is dated back to the second half of the 17th century and belongs to a well-known noble family. Designed by an unknown author, it is made of two floors and has in its façade three different architectonic orders and decorated windows. The main door enters onto an inner courtyard, once used as a stop for carriages and a refreshment room for horses.
