In 1428 another unfortunate event happened: a big earthquake caused damage to the building and a few deaths to those who were praying inside. The earthquake destroyed the Rosetta window that was on the western wall of the church. Between the years 1459-1460 the window was replaced. On both sides of the western gate you will see statues of Peter and Paul.
Inside the Basilica are three wings, spacious and lit by big and high windows of the structure. In 1936 another fire erupted in the building, during the rebellion against the priests. Many art pieces in the church were destroyed and lost. Among them was the Baroque alter that was here.
The Basilica of Santa Maria del Mar plays an important and main role in the famous novel 'Cathedral of the Sea" written by Ildefonso Falcones.
