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:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
