The Roman circus of Mérida was used for chariot racing. It was modelled on the Circus Maximus in Rome and other circus buildings throughout the Empire. Measuring more than 400 m in length and 30 m of width, it is one of the best preserved examples of Roman circus. It could house up to 30,000 spectators.
There is no consensus about the circus' dating, as it was built and used for several years before its official dedication. It seems to have been built sometime around 20 BC and inaugurated some 30 years later. It was located far outside the city walls, but close to the road that connected the city to Toledo and Córdoba.
After the fall of the Western Roman Empire and the rise of Christianity in Spain, the circus saw more use than the other Roman structures of Mérida, since racing was considered less sinful than spectacles performed in the Theatre and the Amphitheatre.
Mérida's circus remains very well preserved with numerous structures, including the Porta Pompae ('main entrance'), the Porta Triumphalis ('triumph gate'), the spina (the longitudinal wall), the tribunal iudicium ('tribune of the judges'). A museum dedicated to the circus now sits near the middle edge of the circus grounds and it allows admittance into the fenced area around the circus remains.
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.
