Located in the heart of the old town area of Valencia is Plaza de la Reina. This is a pretty square, with flowers in the middle, and cafes, restaurants and grand buildings around the edge. The one thing you can't help but notice when you are in the square is the Cathedral and bell tower, which stand at its northern end. Just off the square, at the south west end, is the small Plaza Santa Catalina, where you can visit Iglesia de Santa Catalina.
