La Seu, as the Cathedral of Santa Maria is known, dominates the maritime façade of Palma. Construction on it began in the early 14th century, in the place formerly occupied by the Muslim mosque. The oldest part corresponds to the central apse, and at the end of the 14th century work began on the Mirador portal, a magnificent example of the island’s Gothic splendour, constructed under the direction of Pere Morei. On the inside, with three naves and eight chapels on either side, one can perceive the cathedral’s singularity, marked as it is by space and light. The larger rose window, known as the Ojo del Gótico or ‘Gothic Eye’, is the biggest in Europe in this style. In the early 20th century, Antoni Gaudí directed some remodelling work on the cathedral, contributing to it by installing wrought iron elements and fitting baldachins, for example. And in 2007, Miquel Barceló created the ceramic skin that covers Capella del Santíssim.
