The Panóias Sanctuary, 'Fragas de Panóias', is located in Vale de Nogueiras, in the municipality of Vila Real. Its construction dates back to the end of the 2nd century - early 3rd century AD.
The sanctuary is an enclosure with three large rocks, where several cavities of various sizes were opened and access stairs were also built.
On the rock located at the entrance of the enclosure, several inscriptions were engraved - three in Latin and one in Greek , describing the ritual celebrated, the gods to whom it was dedicated and who it dedicated.
The sanctuary is composed of tanks of different sizes and shapes, votive inscriptions, building foundations, and access steps. Everything was carved in the granitic rocks outcrop.
Today, only three inscriptions remain in Latin and one in Greek. They contain the instructions of the rituals celebrated, the identification of the gods, and who dedicated the site, Gaius C. Calpurnius Rufinus, a member of the senatorial order.
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.
