Hi! You can see in the following picture the Barcelona Cathedral and Ramon Berenguer III statue.
As you can deduce, this is not the entry of the Cathedral, the photo was taken from the left side, near the crowded street of Via Laietana. This side was reformed in the last year 2017, surrounding walls were removed and the pit was leveled with the help of stairs.
Barcelona Cathedral was built upon a romanic church (built upon a Visigoth (built upon a paleochristian) church) between XIII and XV century. However, the facade is from XIX century.
