The original building of the current cathedral in Gibraltar was built during the Spanish period. Just after the reconquest of the city to the Moors, the main mosque was decreed to be stripped of its Islamic past and consecrated as the parish church. However, under the rule of the Catholic Monarchs, the old building was demolished and a new church was erected, in Gothic style. The cathedral's small courtyard is the remnant of the larger Moorish court of the mosque. The Catholic Monarchs' coat of arms was placed in the courtyard where it can still be seen today.
Due to the building being severely damaged during the 1779–1783 Great Siege, in 1790 the then Governor of Gibraltar Sir Robert Boyd offered to rebuild the cathedral. The reconstruction took place in 1810 and the opportunity was also taken to widen Main Street. The clock tower was added in 1820 and in 1931 restoration work was carried out on the cathedral and the current west façade erected to replace the poorer one built in 1810.
Until the 19th century, anyone who died in Gibraltar had the right to be buried under the cathedral floor. Bishops are buried in a crypt beneath the statue of Our Lady of Europe.References:
The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
