Pembrokeshire is the fifth-largest county in Wales, but has more scheduled monuments (526) than any other local authority area except Powys.
With three-quarters of its boundary being coastline, Pembrokeshire occupies the western end of the West Wales peninsular, terminating with the tiny cathedral city of St David's.
Also scheduled are many Medieval castles, mottes and baileys, priories, chapels and churches, houses, town walls and a Bishop's palace, along with a wide variety of post-medieval sites from coalmines, kilns and dovecotes through to 19th and 20th century coastal defenses.
The compilation of the list is undertaken by Cadw Welsh Historic Monuments, which is an executive agency of the National Assembly of Wales.
