In the image above, detail of two cathedrals are shown. The Romanesque style of the old cathedral is shown in the Torre del Gallo, and to the right, the dome of the New Cathedral.
On this photo, you can see the Cathedral taken from what remains of the Wall, that once surrounded the city of Salamanca.
There are two cathedrals in Salamanca, the Old Cathedral is a Romanesque style building, constructed on the first half of the twelfth century and completed on the thirteenth century. This Cathedral is located to the left of the above picture, next to the New Cathedral.
The tower of the new cathedral, was built on the bell tower of the Old Cathedral. It had to be reinforced in the eighteenth century, after the Lisbon earthquake.
The new cathedral was built between 1513 and 1733 while retaining the old, just next to it. At first, it was decided to demolish the old temple, although the criterion was imposed to keep it for worship while performing new construction, and the idea of destroying it was reconsidered, and it has been preserved. On the picture above, you can see the main facade of the New Cathedral. Below the picture shows part detail of both Cathedrals, the Romanesque Torre del Gallo, from the Old Cathedral and the New Cathedral dome.
