Situated on a cliff overlooking the mouth of the Chagres River are the ruins of the ancient Spanish Fuerte San Lorenzo (San Lorenzo Fort). The fort was build in 1597 as part of the fortification to protect the coast from pirate attacks. In 1671 the fort was captured by pirate Henry Morgan and used like a base for his attack on Panama City. The fort was defended by 314 Spaniards and only 30 survived the attack. On his return, Morgan completely destroyed the fort. Six year later the Spanish rebuild the fort with additional cannon batteries and barracks. This new fort was destroyed by the British Admiral Vernon in 1740. In the 1750 the fort was rebuilt again and this structure can be seen in present days. Fort San Lorenzo was declared a World Heritage Site by UNESCO in 1981
