Walk along the cobblestone streets of atmospheric San Juan and see landmarks from various centuries that show the architectural and cultural transformation of downtown. Being founded in 1521, San Juan offers a wealth of historical attractions. Many of them date to the 16th century such as the fortification El Morro, San José Church – the second-oldest church in the Americas – and the original main gate into San Juan that was built in a defensive wall 20 feet thick. The stories behind their construction are fascinating. You will also meander through several of the most popular public areas such as Plaza de Armas, a square laid out in colonial times, and Quincentennial Plaza, which was built in 1992 to commemorate the 500th anniversary of Columbus’ first voyage to the Americas. The now trendy neighborhood La Perla has probably changed the most as it was once among the poorest areas. The guide will describe its inspiring transformation.
