GIS spatial data for Scheduled Monuments, part of the National Heritage list for England. Scheduled monuments are represented by a polygon defining the extent of the statutorily protected area.
Scheduling is applied only to sites of national importance, and even then only if it is the best means of protection. Only deliberately created structures, features and remains can be scheduled. There are almost 20,000 Scheduled Monuments on the List. Scheduling is reserved for carefully selected sites, which create a representative sample of sites from different epochs.
