Built by the Crown of Aragon on the site of a Moorish-era mosque, Palma cathedral is 121 metres long, 55 metres wide and its nave is 44 metres tall.
Designed in the Catalan Gothic style but with Northern European influences, it was begun by King James I of Aragon in 1229 but only finished in 1601. It sits within the old city of Palma atop the former citadel of the Roman city, between the Royal Palace of La Almudaina and the episcopal palace. It also overlooks the Parc de la Mar and the Mediterranean Sea.
Light pours in through the rose window - one of the world's largest, 12m across and studded with 1,236 pieces of stained glass. The columns are ringed with wrought-iron candelabra designed by Gaudi. His most controversial addition is the unfinished Crown of Thorns, fashioned from cardboard and cork and suspended above the altar. Be sure to walk around to the south front, facing the sea, to look at the Portal del Mirador a 15th-century door by Guillem Sagrera featuring scenes from the Last Supper.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
