Cathedral of San Juan Bautista, San Juan (must see)

The Cathedral of San Juan Bautista is the Roman Catholic temple and the seat of the Archdiocese of San Juan de Puerto Rico. This is one of the oldest buildings in San Juan and the second-oldest operational church in the Americas. Traditionally, travelers entering San Juan Gate would make this cathedral their first stop in the city to thank God for their safe journey.

It sits on the site of a grammar school, established in 1513 by Bishop Alonso Manso. This was the first school in Puerto Rico (and the oldest school in the United States after Puerto Rico became a US territory). Here, the Latin language, literature, history, science, art, philosophy, and theology were taught free of charge.

The very first, wooden, church on this spot was built in 1521. It was destroyed by a hurricane, and the current temple of stone was built in its place, in 1540. The church was remodeled several times over the course of centuries, most recently in 1917.

The cathedral contains the tomb of the Spanish explorer Juan Ponce de León. It also houses a shrine dedicated to the Blessed Carlos Manuel Rodríguez Santiago, the first Puerto Rican and the first Caribbean-born layperson (much as the first layperson in the history of the United States) to be beatified.

The Cathedral of San Juan Bautista is also unique as a rare example of medieval Spanish architecture in the New World.
