The Historical City of Ayutthaya is split up into two main areas being the Historical Park - a UNESCO World Heritage site (Pratu Chai sub-district) and the area outside the Ayutthaya Historical Park (sub-districts of Pratu Chai, Tha Wasukri and Ho Rattanachai), called here Ayutthaya Historical City, within the boundaries of the city island. This page is about the area within the city island but excludes the Historical Park.

The Ayutthaya Historical City has 104 monastic sites.
