The Castillo de los Moros was built in the 18th century in what is now the Santa Lucía neighborhood. The castle is located on the hill of the Moors, from which it takes its name, and which, prior to its fortification, had proven to be a strategic position for the defense of the square, when during the war of the Spanish succession it was used by the Philippian artillery of the Duke of Berwick to end the Austracist resistance of the Castle of Concepción (1706).
The construction was designed by the Mirobrigense military engineer Juan Martín Cermeño in the context of the process of improvement of military structures in Cartagena in the reign of Carlos III , and that was motivated by the appointment in 1726 of the city as capital of the Mediterranean Maritime Department. The works were finally directed by the Croatian Mateo Vodopich between the years 1773 and 1778.
The castle of the Moors was ceded by the Ministry of War to the Ministry of Finance on June 19, 1921. In 1925, Mayor Alfonso Torres López proposed to locate in it the jail of the judicial district , but ended up rejecting the idea in favor of a plot in San Antonio Abad. The possession of the fort would definitively pass to the Cartagena City Council on September 24, 1929, without any use or care being given to it since then, which is why its current state is of prolonged deterioration.
The castle rises to an altitude of 56 meters above sea level and was built following the parameters of the neoclassicism of the French-speaking Spanish school. On many occasions it has been referred to as a hornabeque , although there is consensus that it is a crowned work.
The building was designed to protect the bastioned front of the Hospital de Marina and at the same time the Gates of San José, one of the three monumental entrances to the city, which was reduced to the old town surrounded by the walls of Carlos III.
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.
