The Bridge of Cava da Velha (Ponte da Cava da Velha) is a Roman bridge, situated in the civil parish of Castro Laboreiro e Lamas de Mouro, in the municipality of Melgaço. The name Ponte Nova indicates the existence of another structure constructed in the same local (or nearby) at one time anteceding the current bridge. This may actually be the nearby Ponte de São Brás or Ponta da Assureira.
The bridge linked the Roman road to Espanha. The bridge was largely constructed in the 1st century, but does not appear in the two most comprehensive lists of Roman bridges. During the Middle Ages, the bridge was reconstructed to take on its current form.
The bridge is situated in an isolated, rural area within the Nature Park of Peneda do Gerês. A bucolic location links riverbank between two Roman-era pavements, that is located 200 metres from the Bridge of Assureira and Chapel of São Brás. The ramp arches are supported on the granite margins.
The structure, in irregular stone, has supported by worked ashlar with joints filled by smaller stones horizontally. Between the arches are prismatic starling upstream, and rectangular buttresses downstream. On the bottom of the arches are holes to fit the frame. The pavement is formed by large irregular slabs, protected by stone slab guards.
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.
