Church of Mercy

Viseu Cathedral began to take shape in the 12th century as a Romanesque building. The current Gothic cathedral, whose construction began in the 13th century, followed the lines of the original Romanesque building, thus endorsing a Romanesque, rather than Gothic, style that is typically spacious. In the Manueline period, the cathedral of Viseu interventions were undertaken inside and in the cloister. In the 17th century, the façade fell down and had to be repaired, and the choir was also renovated.

The Church of the Venerable Third Order of the Nossa Senhora do Monte do Carmo dates from the end of the 18th century. The Church was created as a result of a disagreement between the friars of the Franciscan Order. The unfortunate Franciscan friars abandoned the Capuchin friars and, with the support of the Discalced Carmelites, decided to create the Third Order of Mount Carmel. They proceeded to elect the Table of the Order and in 1735 the foundations of the new church were laid. The ceiling of the high choir was painted in 1862 by the painter Viseense António José Pereira.

The church of Terceiros de São Francisco dates from the second half of the 18th century. Its façade, designed by António Mendes Coutinho, a disciple of Nicolau Nasoni (1691-1773), was widely copied for other churches in the city. In the "Casa do Despacho" there is a small museum space.
