Two days ago we left Madrid and took a fast train to Córdoba. The train was insanely quick, and went as fast as 269 kilometers an hour.
In Córdoba we visited the only shul left, saw a statue of Rambam, went inside the Mosque-Cathedral, climbed the Bell Tower, ate at a restaurant with Sephardic food, saw the Roman Bridge, and went to a Hammam (Arab bath).
There are only three remaining pre-inquisition synagogues in Spain (2 in Toledo and 1 in Córdoba) and we have now been to all three. These remaining synagogues were saved because they all became churches in the 15th century.
Córdoba is not as big as Madrid, but it is no small town. For some time it was the capital of the world and of the Muslim empire.
The Jewish quarter in Córdoba is one of 19 Jewish quarters in Spain, all of which have ספרד/זכור Spain/remember tiles.
Personally, I liked Córdoba a lot more than Madrid and I highly recommend anyone who goes to Spain to visit Córdoba.
