The Ancient Theatre of Epidaurus was dedicated to the ancient Greek God of medicine, Asclepius. It is built on the west side of Cynortion Mountain, near modern Lygourio. It is considered to be the most perfect ancient Greek theatre with regard to acoustics and aesthetics. Because of its exceptional architecture and aesthetics, the theatre was inscribed on the UNESCO World Heritage List in 1988 along with the Temple of Asclepius.
According to Pausanias, the ancient theatre was constructed at the end of the 4th century BC, circa 340-300 BCE, by the architect Polykleitos the Younger. At a maximum capacity of 13,000 to 14,000 spectators, the theatre hosted music, singing and dramatic games that were included in the worship of Asclepius. It was also used as a means to heal patients, since there was a belief that the observation of dramatic shows had positive effects on mental and physical health.
Today, the monument attracts a large number of Greek and foreign visitors and is used for the performance of ancient drama plays.
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.
