Belize City is the largest city in Belize. It was once the capital of the former British Honduras. According to the 2010 census, Belize City has a population of 61,461 people. It is at the mouth of the Haulover Creek, which is a distributary of the Belize River. The Belize River empties into the Caribbean Sea eight kilometres from Belize City on the Philip Goldson Highway on the coast of the Caribbean. The city is the country's principal port and its financial and industrial hub. Cruise ships drop anchor outside the port and are tendered by local citizens. The city was almost entirely destroyed in October 1961 when Hurricane Hattie swept ashore. It was the capital of British Honduras until the government was moved to the new capital of Belmopan in 1970.
