Brighton has a long history as a popular seaside resort town on the southern coast of England. It was first mentioned in the Doomsday Book in 1086 and saw growth as a fishing and port town in the 16th-17th centuries. In the 18th century, doctors began promoting the health benefits of sea bathing, attracting more visitors. Major growth occurred in the 19th century with the construction of the Brighton Pavilions by the Prince of Wales in 1787 and the arrival of the London to Brighton Railway in 1841, opening the town to day trippers. The development of tourism infrastructure like the two piers further increased visitor numbers. Today, tourism remains a vital part of Brighton's economy.
