Weymouth is a large seaside town in Dorset, England, situated on a sheltered bay at the mouth of the River Wey on the English Channel coast. The town is 13 kilometres (8 mi) south of Dorchester and 8 kilometres (5 mi) north of the Isle of Portland. The town's population is 52,950 (2006) with a catchment population of 71,700 (2001). The A354 road bridge connects Weymouth to Portland, which together form the borough of Weymouth and Portland. The history of the borough stretches back to the 12th century; including involvement in the spread of the Black Death, the settlement of the Americas, the development of Georgian architecture, and preparations for World War II.
Fishing and trading employ fewer people in the area since their peak in earlier centuries, but tourism has continuously increased its presence in the town since the 18th century and is now the primary industry. Weymouth is a tourist resort, and its economy depends on its harbour and visitor attractions; the town is a gateway situated half-way along the Jurassic Coast, a World Heritage Site on the Dorset and east Devon coast, important for its geology and landforms. Weymouth Harbour is home to cross-channel ferries, pleasure boats and private yachts, and nearby Portland Harbour is home to the Weymouth and Portland National Sailing Academy, where the sailing events of the 2012 Olympic Games will be held
