The church of Santa María in the town of Santa Marta de Tera, Zamora, was built towards the end of the 11th century as part of a monastery of which there are no longer any remains. On June 3, 1931 the church was declared an Asset of Cultural Interest.
This temple is an important Jacobean enclave, which marks the beginning and end of one of the stages of the Camino Sanabrés to Santiago, a branch from the Vía de la Plata. It emphasizes the sculpture of the Apostle Santiago of round bulk, considered by most scholars the oldest known representation of the pilgrim Santiago.
It is also important the phenomenon that takes place in the spring and autumn equinoxes, by which the capital of the saved soul is illuminated by the sunlight that enters through the oculus of the gable of the header and that every time concentrates a greater number of visitors.
