Meanwhile, the original colonial settlement at the eastern edge of the harbour called ''Saint Louis'' after King Louis IX of France, later known as Port Louis, was found to be subject to flooding and malaria, so a new town was constructed called ''Ville de Fort Royal'' ("Fort Royal Town"). When the island was ceded to Great Britain by the Treaty of Paris in 1763, the new administration renamed it Saint George's Town, after the patron saint of England and ''Fort Royal'' was renamed Fort George, after King George III. On 1 November 1775 there was a fire in the town of St. George's known as the great fire of St George's. After the great fire of 1771, most of the boarding houses on Granby Street were moved to Gouyave.
