The castle of Alcalá la Real (or Fortaleza de La Mota) dates to the 13th-14th century, although some elements of the structure are older. La Mota was the last great defensive bastion before Granada as it is reached from Jaén and Córdoba. It’s conquest by Castile was very hard. In 1213, and for the first time, Alfonso VIII conquered the Almohades.
After the Christian conquest, at the beginning of the 13th century, the valuable fortress of La Mota fell once again into Muslim hands. It was not until 1341 that Alfonso XI forced the capitulation of the city through his conquest. After the conquest, Alfonso XI destroyed the Mezquita Mayor (Grand Mosque) and built, in the very same place, the first Iglesia Abacial with a Gothical style.
Its political and military importance increased during the final period of the Reconquest, in the second half of the 15th century, particularly during the 12 years in which the Catholic Kings waged war to conquer Granada. In this period, Alcalá la Real was declared “a very noble and very loyal town. Key, guardian and defender of the Kings of Castile.”
During the 18th century began the decline of the town of La Mota. A new urbanisation and repopulation program of los Llanos de Alcalá la Real started. Convents, churches and commercial areas were also built which led to an exodus of the population from the old medieval enclosure.
In 1812, Napoleonic troops burnt down the area and completely destroyed the place.
Some of the remains preserved include the abbatial church of Santa María la Mayor, a Gothic-Renaissance church (16th-17th centuries) that was abandoned, like the rest of the site, in the 18th century, when the inhabitants moved to the plain where the town is today.
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.
