Montbrió de la Marca is a small nucleus belonging to the municipality of Sarrat, in the Conca de Barberà region (Tarragona).
It is located on the slopes of a promontory where the old castle of Montbrió was located, from the 11th century. Very close to the location of the castle, in the upper part of the town, the church of Sant Llorenç was erected, documented as early as the 12th century. Originally in a transitional style between Romanesque and Gothic, later reforms ended up giving it a Baroque appearance. It has a small dome and is crowned by a belfry bell tower.
