The origin of the population (Monte del Buey) is not well known, but by the middle of the 6th century it already appeared as the geographical boundary of the diocesan territory of Bracarense. In the 12th and 13th centuries, Mombuey belonged to the Order of the Temple and was a bailiwick. An enigmatic work, the Tower, slender, rectangular (2.5 x 4 meters) and pyramidal, remained as a vestige. It has an advanced Romanesque style, unique in its genre. It is built in small ashlars of gray-green sandstone. On a blind base it shows three bodies communicated internally by a wooden staircase. Closing the construction, a graceful capital of curved planes and irregular openings appears, being in its interior a vaulted refuge room that is acceded by an external passage in the form of a very flown balcony that, on two great corbels, also served as a matacan.
The ornamentation is strange: on the capital and on each front, three folded shreds of unknown meaning are repeated, which, however, have a finish similar to that of the existing ones in the vestments of the Romanesque Virgin and of the Crucified Christ, also Romanesque. The capital starts from a cornice adorned with balls, flowers, leaves and anthropomorphic motifs, all carved with great perfection, highlighting the bust of an ox, stone symbol of other cults. The vaulted shelter of the upper part is said to have room for forty people standing (forty is a number frequently repeated in the Scriptures) and its only access is through the balcony, from the outside, although there is no staircase. The tower was never attached to the church (today yes) and has no sign of having served for the defense of the area. Today the tower has been attached to the church as a bell tower and restored with sgraffito typical of the buildings in the area that completely hide the folded shreds of the roof.
The Romanesque Virgin, from the same period as the tower, appeared in 1987 on an open window in the eastern wall and behind a Baroque altarpiece. It is made of polychrome stone: the Virgin holds the Child on her left knee and holds the Apple of Paradise in her right hand. From a somewhat later period, but not of lesser interest, is the Christ.
