The spiritual and architectural centerpiece of Old San Juan began construction in 1540 as a replacement for a thatch-roofed chapel that was blown apart by a hurricane in 1529. Chronically hampered by a lack of funds and a recurring series of military and weather-derived disasters, it slowly evolved into the gracefully vaulted, Gothic-inspired structure you see today. Among the many disasters to hit this cathedral are the following: In 1598, the Earl of Cumberland led the British Navy in a looting spree; in 1615, a hurricane blew away its roof; in 1908, the body of Ponce de León was disinterred from the nearby Iglesia de San José and placed in a marble tomb near the transept, where it remains today (see the box “Ponce de León: Man of Myth & Legend,” in chapter 2, for more about Ponce de León). The cathedral also contains the wax-covered mummy of St. Pio, a Roman martyr persecuted and killed for his Christian faith. The mummy has been encased in a glass box ever since it was placed here in 1862. To the right of the mummy is a bizarre wooden replica of Mary with four swords stuck in her bosom. After all the looting and destruction over the centuries, the cathedral’s great treasures, including gold and silver, are long gone, although many beautiful stained-glass windows remain. The cathedral faces Plaza de las Monjas (the Nuns’ Square), a shady spot where you can rest in front of Hotel El Convento.
