The parish church of Quintana del Pidio is dedicated to Santiago Apóstol. It is known that there was an old parish church in Quintana, of Romanesque origin. Its only remains are a walled doorway with a semicircular arch located between the altar and the pulpit; a window with a semicircular arch that is transferred to the south wall of the church and the baptismal font, a real jewel due to its antiquity. However, as happened in many other towns over the centuries, due to population growth, the sacred space became too small, so it was necessary to undertake major extension works that gave rise to the current building.

The church building is Renaissance(16th century). Inside the church there is a Renaissance-Mannerist main altarpiece (late 16th century), which includes the reliefs of Santiago Matamoros and two other Nativity scenes. Also outstanding in the pulpit are the bas-reliefs representing the four evangelists. The canvases of the main altar, the side altarpieces, the images in the chapel of Christ and the front of the church can be properly ascribed to the Baroque period (17th century). The altar of San Sebastián and that of the chapel of Christ belong to the Baroque-Rococo style (18th century).

The ground plan of the church is of the so-called hall or basilica type, consisting of a single nave.

The roof of the church also has a ribbed vault.

The overall structure, due to the type of vaults, attached pillars and columns, shows that it was built during the 16th century.
