It is a center for citrus-fruit packing and has commercial fishing and seafood-processing industries as well as varied light manufacturing. It is also a tourist city, with 8 mi (11.3 km) of white sand beaches. A Spanish Franciscan mission was established there in 1696. Colonists arrived in 1767, but the settlement did not prosper until the advent of the railroad in the mid-19th cent.
