Castillo San Felipe del Morro, (El Morro) by Waalewiener
" El Morro '' fortified in 1539, finished in 1589, 140 feet above sea level, 18 ft thick walls. The Fort only fell once to a land assault by the Earl of Cumberland forces.The Fort is a maze of Tunnels, Dungeons, Barracks, Outpost, and Ramps. There were many restorations and expansions to make the Fort what it is today. The area is a 74 acre site and it has been a National Historic site since 1949. Tours are available , Tour office is open 9-5, and admission is free.Seeing all the colourful buildings the Forts , the Ships in the harbour etc etc
I wish we could have spent more time in San Juan.
