floors higher; the use of various structures achieved a harmonious and ornamental design, with a pyramid-shaped crown and a lantern as a final element, with four light bulbs permanently lit. It rises to seventy-five metres. In 1833 a clock was placed on each side of the tower by Andrés Antelo, commissioned by the Archbishop Rafael de Vélez. As part of its mechanism it has two bells, one, at the hour, called Berenguela, and a smaller one marking the quarter hours. These two were cast in 1729 by Güemes Sampedro. Berenguela has a diameter of 255 cm and a height of 215 cm, weighing approximately 9,600 kilos, and the smaller weighs 1,839 kilos with diameter 147 cm and height 150 cm. Both original bells cracked, forcing their replacement. The current replicas were cast in Asten (Netherlands) by the Eijsbouts house in 1989 and were placed in the cathedral in February 1990. Interior The cathedral is 97 m long and 22 m high. It preserves its original, barrel-vaulted, cruciform, Romanesque interior. It consists of a nave, two lateral aisles, a wide transept, and a choir with radiating chapels. Compared with many other important churches, the interior of this cathedral gives a first impression of austerity until one enters further and sees the magnificent organ and the exuberance of the choir. It is the largest Romanesque church in Spain and one of the largest in Europe. The Pórtico da Gloria The 12th-century Portico da Gloria, behind the western façade, is in the narthex of the west portal. It is a remain from the Romanesque period, a masterwork of Romanesque sculpture built between 1168 and 1188 by Master Mateo at the request of king Ferdinand II of León. The vigorous naturalism of the figures in this triple portal is an expression of an art form, varied in its details, workmanship and polychromy (of which faint traces of colour remain). The shafts, tympana and archivolts of the three doorways which open onto the nave and the two aisles are a mass of strong and vibrant sculpture representing the Last Judgment. The central tympanum gives an image of Christ in Majesty as Judge and Redeemer, showing His wounds in His feet and hands, accompanied by the tetramorph. He is surrounded on both sides by a retinue of angels carrying the symbols of the Passion. In the archivolt are represented the 24 Elders of the Apocalypse, who
