Iglesia de San Pedro, Gothic parish church in Lugo, Spain

The Iglesia de San Pedro is the former conventual church of the Franciscan monastery of San Francisco in Lugo, built in granite in the Gothic style. It has a Latin-cross plan with a nave, transept and side chapels, and its main chapel was financed from the 14th century by Pedro Enríquez de Castilla, count of Trastámara, who planned his burial there.

The Franciscan convent was documented by 1282, when the friars signed a friendship pact with Lugo's Dominicans and divided a purchased property. In the 14th century the counts of Trastámara became patrons: Pedro Enríquez funded the main chapel, continued by his son Fadrique. A fire on 8 December 1638 spared only the stone church and cloister. In 1809 troops used the church as a stable, and in 1835 the Desamortización closed the convent.

The church was ceded in 1867 to the Venerable Orden Tercera, which restored it so it could reopen for worship on 10 February of that year. The Franciscans had left Lugo in 1835 under the Desamortización de Mendizábal, and the former convent buildings later housed a poorhouse, a maternity house and the municipal theatre.

The church is located directly within Lugo's well-preserved Roman walls in the old town, making it easily accessible on foot. The main entrance features large granite blocks with a generous window above that fills the interior with natural light during the day.

The church is the only surviving part of Lugo's Franciscan convent besides the cloister: a fire on 8 December 1638 spared both because they were built almost entirely of stone. The convent buildings later housed a poorhouse, a maternity house and the municipal theatre, while the church itself served as a prison and municipal warehouse.
