The Welsh town of Caerphilly is located at the Rhymney Valley's southern end and has a population in the region of 31,000. It serves as a commuter town to Cardiff and Newport, which are 12kms and 19kms away, respectively. The most famous site in the town is Caerphilly Castle, which was built between the years of 1268 and 1271. It is the biggest castle in Wales and the second biggest in the UK. Many historians visit the castle each year as it was Britain's first truly concentric castle and is regarded as one of Western Europe's great medieval castles. The castle stands on a 30-acre site and boasts a tower that has a greater lean than Pisa's tower. It is also said to receive regular visits from the so-called ghost of the Green Lady, the spirit of the wife of Gilbert de Clare, the Earl of Gloucester responsible for constructing the castle. Caerphilly hotels can be found throughout the town, which in addition to its castle is famous for its cheese. Tourists can purchase this tasty delicacy in the town's local shops. There is also an excellent selection of restaurants, coffee shops and pubs on offer, and once a year in July is the town's International Summer Festival, which provides attractions such as folk dancing and street entertainment.
