The city and county of Swansea covers, in addition to the port city of Swansea, areas of upland to the north, and the Gower peninsula to the west. It is on Gower that the earliest scheduled monuments are found. Three sites have evidence of habitation from the Paleolithic, a time before the last ice age. These include the oldest rock painting in Britain and the earliest known burial in Western Europe. There are in total 124 scheduled sites. Prehistoric sites of many sorts are found, particularly on Gower. 64 pre-historic sites are from Paleolithic to Iron Age dates, and include caves, burial mounds and tombs, cairns, defensive enclosures, hillforts and promentary forts. Roman and early medieval sites, by contrast are scarce. The post-Norman Medieval period, by contrast, has 26 sites, 17 of them castles or other defensive monuments. The other nine are all ecclesiastical monuments. The 26 post-medieval monuments are more diverse, including industrial and maritime sites, but also leats, quarries, a mill and even an observatory and an orchid house. All of the Swansea administrative area lies within the historic county of Glamorgan.
