When we speak of the Cathedral of Salamanca in fact we are referring to two churches joined together. First, there is the old cathedral dating from the 12th-13th centuries; and then the new one from the 16th century.
The Old Cathedral is in the Romanesque style with the outstanding Gallo Tower. Inside this temple, the construction of which began at the end of the 12th century, is the San Martín or Oil Chapel. The main reredos, which dates from the 15th century and was created by several painters with Dello Delli at the head, is also worthy of note.
