In some Romanesque or Gothic monasteries, the entrance to the chapter house has an elaborate façade with a door surrounded by highly decorated archivolts, especially when it is a separate building. Many chapterhouses feature elaborate carving or frescos, which include some masterpieces of religious art, but were also sometimes secular. The paintings from Arlanza, now spread across museums in Spain and the United States, originally decorated the monastery of San Pedro de Arlanza, and contain huge bold mythical beasts that are some of the finest survivals of Romanesque palace decoration. In modern settings, the chapterhouse may simply be or use an ordinary office boardroom or meeting room. When it is a separate building, this often consists of just the single main room.
