I'm not sure why this sight isn't mentioned in many tourist guides (new?), but I wouldn't miss Jesuitas if you're visiting Toledo. It is a small church near the Visigoths museum, with two towers and a walkway that you can visit (reminds me of Notre Dame).

It cost less than 2 euro in Jan. 07, and the views of Toledo from the towers / walkway is pretty cool. The church itself is pretty, too, but it's all about the view. The climb isn't bad, and supposedly it is the tallest point in Toledo (so told by the guy at the desk).
