Even though there's only one little mosque in Toledo, all the buildings in Toledo show strong Moorish influence in the architecture. The Church of San Roman, pictured here with the beautiful frescoes, is a good example. It looks like a mosque covered with paintings of apostles, but it was actually built from the start as a church. It now houses a boring Visigoth museum, but it's well worth seeing the church and ignoring the exhibits. The plainer arched building shown here is one of Toledo's two synagogues, which looks identical to a mosque. Actually Toledo's most famous church is Santo Tome, but that's just because of one El Greco's painting, his most famous. You'd have to really like the painting, because the church itself is ugly, so I didn't include a photo.
