Monument dating from the 15th century (1404). It is one of the most important monuments in the village, with granite construction, Gothic style and Mannerist features.
It is not known for sure who ordered the construction of the Igreja Matriz, however it is presumed that the initiative for the project, taken during the reign of King João I, came from one of these men: Nuno Álvares Pereira (born in the county and national hero ) or Álvaro Gonçalves Camelo (Prior of Crato and whose tomb can be seen inside the church). It was built in 1404, under the ruins of an old temple that had existed in the same place, with Jhoane Anes Pietro de Ourê being responsible for the work of the new church, which was dedicated to São Pedro. The building is divided into three naves, marked by ogival Gothic arches covered with polychrome tiles from the 15th century, supported by granite columns with chambraded edges.
In the chancel, we can see the exuberant altarpieces in Baroque gilded carving in the national style, by Porto carvers Domingos Nunes and António Gomes (1685), for the price of 300 thousand réis and later gilded by Francisco da Rocha. Before this altarpiece, there was another altarpiece in the chancel, in the Mannerist style, painted by a royal artist of Philip II, Fernão Gomes (1548-1612), consisting of two boards that survived, one of them the large panel “São Pedro Patriarca” and, at the top, the oval tablet “Martírio de São Pedro” with influence of Italian-Flemish Mannerism.
Reference is also made to the walls of the chancel, lined with tiles, and to the pulpit in stonework, supported by a column. The two side altars are dedicated to Our Lady of the Rosary and the Holy Spirit. The wooden trough ceilings are distinguished by the painted coffers with stylized motifs forming wreaths. In the sacristy, there are the late Mannerist boards of “Pentecost”, “Birth of the Virgin”, “Presentation of the Virgin in the Temple”, “Annunciation” and “Assumption of the Virgin”, paintings from the second quarter of the 17th century.
Next to the Porta do Sol, a commemorative inscription confirming the construction of the Church can be seen: “It was a thousand CCCCXLII. This church was built in honor of Sam Pedro and Johanne Anes Pietro de Ourê” (year referring to the Era of César ). In the center you can see a sertã (possible allusion to the toponym), the key of S. Pedro and the Maltese cross; on the side you can see the coat of arms of King João I and the inscription “Santus Petrus de Sartagineor”.
