The gardens were surrounded by colonnades in the form of a peristyle. The main building consisted of four rooms arranged around a colonnaded courtyard ("peristyle"). Unusually, the cella is sited further back with respect to the peristyle. It also has two atriums, the Tuscan and the peristyle atrium. Common places for graffiti are staircases, central peristyle, and vestibule. Excavations have revealed a villa with peristyle, thermae, granary and water tower. Through the pylon gateway leads into a peristyle courtyard, also built by Ramesses II. Restoration and conservation of the Capitol Dome's cantilevered peristyle and skirting occurred in 2012. The northern end of the "tablinum" opens onto a large, open "peristyle", or garden courtyard. It consisted of a peristyle court with two chapel shrines. Between each peristyle sits the Temple of Apollo Palatinus. The 46th and 47th floors comprise a two-story-tall peristyle, supported by eight columns. In the centre of the peristyle are the remains of a rectangular basin. The tower contains four bells within the peristyle. The peristyle in a Greek temple is a peristasis ().
