When people travel to Sevilla and see the sights, most go directly to the Alcázar, Cathedral, and Plaza de España often times overlooking the beautiful Casa de Pilatos in their haste to see the main sights and snarf down as many tapas as possible in whatever time they have in the city.
It's an easy mistake to miss this gem with the nondescript front, but for how plain it is on the outside, the opposite is true of the interior. The inside, especially the courtyard and the tiled rooms directly adjacent to it, are absolutely beautiful.
The patio has the typical intricate carvings above the archways with designs so detailed, that they sometimes don't even look real. The four statues that sit in the four corners stand guard over the little patio, and a sizable fountain bubbles away in the center. Of course, tiles adorn all the walls, and this is seen in all its glory when you step foot inside the connecting rooms which are tiled floor to ceiling save for window and door openings. It's quite spectacular.
If you are lucky enough to arrive at certain times, there are guided tours of the residence upstairs. It also affords you the best views of the entire courtyard.
