The streets behind the docks of the historic Fort Cochin and Mattancherry districts are lined with old merchant houses, godowns (warehouses), and open courtyards heaped with betel nuts, ginger, peppercorns, and tea. Throughout the second millennium this ancient city exported spices, coffee, and coir (the fiber made from coconut husks), and imported culture and religion from Europe, China, and the Middle East. Today Kochi has a synagogue, several mosques, Portuguese Catholic churches, Hindu temples, and the United Church of South India (an amalgamation of several Protestant denominations). The city is spread out over mainland, peninsula, and islands. Ernakulam, on the mainland 2 km (3 miles) from the harbor, is the commercial center and the one-time capital of the former state of Cochin. Willingdon Island, which was created by dredging the harbor, holds several luxury hotels as well as a navy base. The beautiful Bolghatty Island, north of Ernakulam, is a favorite picnic spot for locals. On it there's a government-run hotel in a colonial structure that was once used by the Dutch governor and later by the British Resident. Another local favorite is Cherai beach on Vypin Island, which is a 10-minute ferry ride from Fort Cochin. The Fort Cochin district, Kochi's historic center, is at the northern tip of the Mattancherry peninsula. Houses here often recall Tudor manors; some have been converted to hotels, others remain in the hands of the venerable tea and trading companies. South of Fort Cochin, in the Mattancherry district, is where you'll find the city's dwindling Jewish community. Their small neighborhood, called Jew Town, which is now dotted with cafés and shops selling curios and antiques, is centered on the synagogue.
