Lancaster Roman Fort in the context of "Ruins"

Lancaster (/ˈlæŋkəstər/ LANG-kə-stər or /ˈlænkæstər/ LANG-kast-ər) is a city in Lancashire, England, and the main cultural hub, economic and commercial centre of City of Lancaster district. The city is on the River Lune, directly inland from Morecambe Bay. Lancaster is the county town, although Lancashire County Council has been based at County Hall in Preston since its formation in 1889.

The city's long history is marked by Lancaster Roman Fort, Lancaster Castle, Lancaster Priory Church, Lancaster Cathedral and the Ashton Memorial. It is the seat of Lancaster University and has a campus of the University of Cumbria. It had a population of 52,234 in the 2011 census, compared to the district, which had a population of 138,375.

Over Burrow Roman Fort is the modern name given to a former Roman fort at Over Burrow (or Burrow-in-Londsale), Lancashire in North West England. Today it is the site of the 18th-century country house Burrow Hall. The first castra is thought to have been founded in the first century AD within the Roman province of Britannia.

The fort's Roman name is not known, but is assumed to be one of those recorded in Route X of the Antonine Itinerary. Galacum or Calacum, originally conjectured by William Camden, was still being proposed in 1979. However, in 1998 David Shotter suggested that Galacum would be more appropriately applied to Lancaster and Alone (previously assigned to Watercrook in Cumbria) for Over Burrow. Camden also associated the site with Ptolemy's Καλαγον, one of the cities of the Brigantes.
