HAVANA, CUBA - SEPTEMBER 4: An exterior view of the Santa Isabel Hotel (est. 1867) and the Plaza de Armas, a main tourist square, on September 4, 2004 in old Havana, Cuba. The Plaza de Armas has been carefully restored to maintain the original 16th century Spanish colonial architecture and atmosphere. The square is the oldest in Havana, originally named "Plaza de la Iglesia" (Church Square), but received its present name when the Spanish governorship relocated to Havana in the 16th century, and the Spanish military began to use it for practices, parades, and other military events.
