Old San Juan - City Wall La Muralla

Construction of the La Muralla (the City Wall) in Old San Juan began in 1539 and was completed in 1782. It is built from sandstone blocks and measures 20ft/6m in thickness. You can appreciated the thickness best when passing through the gate.

La Muralla originally surrounded the entire colonial city and effectively guarded San Juan against enemy attack.

The wall is found south of the Bahia de San Juan near the oceanfront, at Paseo and La Princesa, south of Caleta de San Juan.
