Make your way to the Seville Cathedral, also called the Cathedral of Saint Mary of the Sea (Catedral de Santa María de la Sede). Meet your tour guide and group, and enter the cathedral before it is open to the general public.
Marvel at the sheer size of the building, the largest Gothic cathedral in the world. Soak up the ambiance of the nearly-empty space, and enjoy looking around without the presence of the usual crowds.
Walk through the enormous central nave, dominated by a choir box and one of the largest altarpieces in the world, which features carved scenes from the life of Christ. See the city key surrendered to Fernando by the Moorish and Jewish city occupants, inscribed with a final protest. Admire the 15th-century stained glass windows and the intricate iron screens that close off the eighty chapels in the cathedral. The Royal Chapel, or Capilla Real, was the original royal burial chapel and now contains the silver shrine of Fernando III.
Opt to climb La Giralda, originally a Moorish minaret and now the cathedral's bell tower. This tower is 343 feet (105 meters) tall and is a well-known symbol of the city of Seville.
After your tour, feel free to ask questions before heading off to continue exploring Seville.
