Apart from the church of San Giovanni a Mare, Norman buildings in Naples were mainly lay ones, notably castles (Castel Capuano and Castel dell'Ovo), walls and fortified gates.
S výjimkou kostela San Giovanni a Mare byly normanské stavby v Neapoli většinou sekulární, zejména hrady (Castel Capuano a Castel dell'Ovo), hradby a opevněné brány.
