The country's main museum, housed in the Old Courts Building on Harbour Drive — a wood-and-coral-stone structure dating from the 1830s that has been at various times the courthouse, jail, post office, and church meeting hall. The exhibits cover the seafaring, turtle-fishing, and shipbuilding history of the islands, plus a serious natural-history section with corals, fossils, and a 15-foot saltwater crocodile skeleton.
A good first stop for understanding why Cayman is the way it is — the islands had no permanent population until the 17th century, no road off George Town until the 1930s, and no economy other than turtles and shipwrecks until the bank-secrecy laws of the 1960s.
