Cordoba

Another beautiful city, with Roman ruins, the Mezquita, and great food.  I spent a long time in the Mosque-Cathedral.
According to Wikipedia

The [Mezquita-Catedral] was originally built by the Visigoths as the Catholic Basilica of Saint Vincent of Lérins. When Muslims conquered Spain in 711, the church was first divided into Muslim and Christian halves. This sharing arrangement of the site lasted until 784, when the Christian half was purchased by the Emir 'Abd al-Rahman I, who then proceeded to demolish the entire structure and build the grand mosque of Cordoba on its ground.

The mosque was converted to a church after the Reconquista, when a cathedral was built in the interior.
We also toured a synagogue (now a museum).

There are Roman ruins from a 1st century BC temple.

And in general a beautiful city with an historic past.  It is the highest navigable part of the Guadalquivir River, so the Romans chose it as the site of a fortress.  They built a bridge spanning the river.

The old city walls, and some of its gates, are still standing.  We walked miles through narrow streets, shopped, and ate wonderful food.  Me and one of the girls managed to get lost (pretty easy in the narrow, unmarked streets) but eventually we made it back to the hotel.

It is hard for me to imagine living in a place with such a long past.  Texas is so recent - Austin is less than 250 years old.  Cordoba is more than 2000.
