Casa del Mitreo, 'the House of the Mithraeum' is a house built at the end of the 1st century and the beginning of the 2nd century AC outside the Mérida city walls. Its size and the decoration of some of its rooms undoubtedly show that its owners were people of Hellenistic culture who were important within the society of Mérida.
The whole building is set up around three courtyards. You enter the first one through a stairway and you arrive onto a tetra style atrium with a pond to collect water, the impluvium. It seems that this area, like other areas in the house, had a second floor because of the steps that are still preserved. Several rooms come out onto this atrium, built like other ones in the house: a masonry base and the rest of the wall in rammed earth. The walls were plastered and decorated with paintings.
One of these rooms preserves the mosaic of the Cosmos. It represents a colourful and realistic mixed group of human figures that represent the different elements of the known universe, going from terrestrial and marine elements until celestial elements, but they all revolve around the essential figure of Eternity (Aeternitas).
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.
