Old San Juan
Old San Juan © cogito ergo imago
Encompassing about seven blocks, this area dates back about 500 years to the Spanish occupation when it served as a military stronghold that even withstood Sir Francis Drake's armies. The original cobbles on the streets are blue-tinged and were originally used as ballast on Spanish ships. The ancient stones set off the more than 400 restored 16th- and 17th-century Spanish colonial buildings that fill Old San Juan and draw thousands of tourists to walk the narrow, steep streets every day. The old town is enclosed in amazingly thick, high walls, and features numerous attractive plazas bearing sculptures and memorials.
