Convento de Santa Teresa is an austere building with a history that dates back to the 18th-century. It was the pioneer woman convent in the country. The nuns belonged to the order of Saint Clara, but in 1777 adopted the severe rules of the Teresianas which calls for a life of seclusion. Only their superior is allowed to communicate through an ingenious device on the wall of the vestibule. One cannot visit the closure, but in the vestibule there is a fine work in Portuguese tiles, depicting biblical scenes. Access to the church is strictly limited to moments during the religious services.
