Tucked between the Old Cathedral (now Santa Cruz Church) and in the shadows of the New Cathedral’s bell towers is a cluster of four historic buildings called the Halls of the Cathedral Complex. They are approached from Plaza Fray Félix. The Mudéjar style brick spire in the center is the crown of Casa de la Contaduría. The House of Accounting was constructed during the 16th century. This is now the Cathedral Museum. Inside is an interesting collection of religious artifacts, vestments, paintings, sculptures and documents.
