The Church of the Ascension is an Episcopal church built in 1840–41. It was the first church to be built on Fifth Avenue and was designed by Richard Upjohn in the Gothic Revival style. The interior was remodeled by Stanford White in 1885–88.
The brownstone church is symmetrical, and features a square tower. Stanford White's interior design features a pulpit designed by Charles Follen McKim, mosaics by D. Maitland Armstrong, a marble reredos by Louis Saint-Gaudens and several stained glass windows by John LaFarge and his altar mural The Ascension. This is considered to be one of his best works
The parish house designed by McKim, Mead and White took a previously existing building and turned it into a Northern Renaissance-inspired building of yellow brick with bottle-glass windows.
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.
