The provenance of these Towers is the polychrome stone choir that was located in the first sections of the main nave of the cathedral until its demolition in 1604, when they were mostly reused as flooring slabs in the renovation works, thus allowing them to be found. It represents the walls of Heavenly Jerusalem with crenellated and polygonal structures carved with reliefs and finished with pyramid coverings, at times decorated with fish scales and a ball at the top. The pieces have been preserved in good condition.
