Why is "History of Cardiff" trending?

Wikipedia Overview

The history of Cardiff—a City and County Borough and the capital of Wales—spans at least 6,000 years. The area around Cardiff has been inhabited by modern humans since the Neolithic Period. Four Neolithic burial chambers stand within a radius of 10 mi (16 km) of Cardiff City Centre, with the St Lythans burial chamber the nearest, at about 4 mi (6.4 km) to the west. Bronze Age tumuli are at the summit of Garth Hill, within the county's northern boundary, and four Iron Age hillfort and enclosure sites have been identified within the City and County of Cardiff boundary, including Caerau Hillfort, an enclosed area of 5.1 ha. Until the Roman conquest of Britain, Cardiff was part of the territory of an Iron Age Celtic British tribe called the Silures, which included the areas that would become known as Brecknockshire, Monmouthshire and Glamorgan. The Roman fort established by the River Taff, which gave its name to the city—Caerdydd, earlier Caerdyf, from caer (fort) and Taf—was built over an extensive settlement that had been established by the Silures in the 50s AD.
