The church of San Pedro in Teruel is a 14th century church belonging to the Mudejar architecture of Aragon, declared a World Heritage Site. Its bell tower, the tower of San Pedro, is the oldest example of Mudejar architecture in Teruel and dates from the 13th century. The interior of the church was decorated between 1896 and 1902 in the neo-Mudejar modernist style by Pablo Monguió Segura and the plastic artist Salvador Gisbert, who also erected a new cloister. The Lovers of Teruel were buried in one of its side chapels. Since 2005, the Mausoleum of the Lovers, a museum space built next to the church, has been open to visitors.

In 1220, two disciples of Saint Francis of Assisi, Juan de Perusa and Pedro de Saxoferrato, founded a Franciscan convent in Teruel, whose hermitage of San Bartolomé was demolished by order of the archbishop of Zaragoza, García Fernández de Heredia, to begin the construction of the church that can be seen today in 1392.

In 1555, the mummies of the Lovers of Teruel were discovered in the subsoil of one of the side chapels, which from then on would be dedicated to the Chapel of the Lovers. It housed an altarpiece dedicated to Saint Cosmas and Saint Damian, sculpted by Gabriel Joli, the architect of the altarpiece in the cathedral of Teruel, before 1537.

The church has a high single nave of five bays with side chapels between the buttresses, a polygonal apse and a choir loft at the base. It is covered with simple ribbed vaults reinforced by pointed transverse arches and conveys a great sense of unity and spaciousness.

In the western gable of the church there is a large rose window in the upper area and the main doorway in the lower area, opened by means of a rectilinear depressed arch framed by pointed and flared archivolts topped by a gable and flanked by pinnacles, while the secondary doorway is located on the Epistle wall and is similar in structure to the one described above, but of smaller proportions.

Conrat Rey and Gonzalvo de Vilbo, masters who usually worked for the Fernández de Heredia family, were involved in its construction.
