Cardiff is the capital and largest city in Wales. The county, which takes in a number of smaller settlements around the city, has 28 scheduled monuments. These include sites from every period of Welsh history, from the Neolithic onwards. With four hillforts, six castles and six coastal/port sites, they reflect Cardiff's military and strategic role within South Wales. All but one of the sites on this list are within the historic county of Glamorgan. (A small part of the modern unitary authority area was formerly part of Monmouthshire.)(Main article: Lists of scheduled monuments in Wales)
