Pontefract is known as a traditional market town in West Yorkshire, England, close to the A1 (or Great North Road) and the M62 motorway. Until recently part of the West Riding of Yorkshire, it's amongst the five towns in the metropolitan borough of the City of Wakefield and it has a population of 28,250. Pontefract's motto is Post mortem patris pro filio, Latin for "After the death of the father, support the son", a reference to English Civil War Royalist sympathies.
