Torre de Oro

The Torre Del Oro has been around since Seville was the capital of muslim Spain (12th c)...a defense tower next to the port area of the river, it served a military purpose for centuries.  Today it's a museum and a good place to get pictures of the city from above:

The tower in the distance is the Giralda, one of the only parts of the Cathedral that originally belonged to the Mosque.

This bridge is called Triana (as is the neighborhood to the left of the picture.)  The bridge was the first permanent bridge to be constructed in Seville (before it, bridges sat on boats...the river needed to be tamed before a permanent bridge could be constructed)
