Construction of the Iglesia de San Francisco began in 1778, and lasted over 20 years to finish, for which the changing tastes and styles of the times can be clearly seen in its architecture. The facade is purely churrigueresque (excessively ornate), with a plethora of carved stone figures and downward tapering columns. However, the bell tower of this church, built in 1799 by the famed architect Francisco Eduardo Tresguerras, is in neoclassical style as was fashionable at the time.
