Two of the three UNESCO World Heritage Sites of Seville, the Royal Alcazar palace and the Cathedral of Seville are impressive to say the least. The marvelous architecture, romantic gardens, and breathtaking art has to be seen in person to be fully appreciated.
The Cathedral is one of the finest Gothic architectures in all of Europe and, more importantly, the largest Gothic cathedral worldwide. The Giralda tower itself can be seen from virtually every point in the city, and is never a dull sight. You have to see the skyline from atop with your own eyes.
The most visited site in Seville and arguably the most famous in Andalusia, the Royal Alcazar is truly a special palace and even more unique tour. Captured in movies and tv around the world, you must see the palace in person to truly appreciate it.
