Station 19 of 21

Great Palace (Castillo)

At twelve meters high, El Castillo dominates the clifftop skyline. When Spanish explorer Juan Díaz first glimpsed it from his ship in 1518, he declared it the largest tower he'd ever seen. You're standing before the most commanding structure in all of Tulum.

And speaking of commanding views—El Castillo served a remarkably practical purpose alongside its spiritual role. Directly in front of these cliffs lies the only safe passage through the treacherous reef. Priests likely lit fires in small niches along the back wall, guiding trading canoes safely into harbor through the darkness. As you continue toward the scenic overlook, watch for those lighthouse niches in the back wall—silent witnesses to Tulum's role as a thriving maritime gateway.

But this was no castle or fortress, as early visitors assumed. You're looking at a sacred temple, built and rebuilt over centuries as successive rulers added their own layers to this spiritual heart of the city. What you see today is actually the result of multiple construction phases, with at least two earlier temples encased within. This reflects a fascinating Maya tradition—rather than demolishing old structures, they simply built over them, preserving the sacred energy of what came before.
