El Miguelete is the bell tower of the cathedral, in the Gothic style, measuring 50.85 m. up to the terrace.

This type of tower passes from the south of France to the Crown of Aragon. The works began in 1381 under the direction of Andreu Juliá, master of the Cathedral of Tortosa. Later, Pere Balaguer would work on the works. The lower body is completely solid, except for the part of the spiral staircase. In the third body of the tower was the house of the person in charge of ringing the bells until the 20th century.

It is so named because its main bell was baptized on the day of San Miguel (September 29) with the name of Micalet (Miguelete). The name of the bell passed to the tower.
