Blauer Hof was first referred to as a Freihof under Melchior Arguello in 1544. From 1705 Imperial Vice-Chancellor Friedrich Karl Schönborn was the owner, who had the existing structure generously expanded by his favourite architect, Lukas von Hildebrandt, between 1710 and 1720. As of 1756, a large extension was built by the court architect Nicoló Pacassi. Circa 1770 the Belvedere was added. Pacassi modified the building, moving the entrance from the eastern to the northern side.
The interior decoration, insofar as it has been preserved, mainly dates from 1853/54.
The castle theatre was built following designs by Nicoló Pacassi in 1753. On the park entrance side there is a high portico with a curved gable. The wall surfaces are structured by sunken fields and superimposed panels. As regards the interior decoration, only the late baroque painting in the illusionist architecture still remains. The upper zone with volutes, floral garlands and putti was added in the 19th century.

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.
