Just off the central park, you'll find the magnificent ruins of the San José Cathedral, a place that truly captures the city's resilient spirit. While the front section still operates as a church, the real magic lies in the vast, open-air ruins behind it, where you can wander among colossal stone columns and arches that reach for the sky. It’s a peaceful, almost mystical spot, especially as the afternoon light filters through the collapsed domes. You can even explore the old crypts below, though be mindful of the steep steps. There's a small entrance fee to access the ruins, and it's well worth it for one of the most memorable experiences in Antigua.
