The head office of the Hiiumaa Museum has been based in Kärdla since 1998, located in the building known as Pikk Maja (Long House). Pikk Maja was built in the 1830s as a residence for the directors of the Hiiu-Kärdla textile factory. It was since then home to several generations of the Ungern-Sternberg and Peltzer families. During the period of Soviet occupation, different establishments and offices used the building.
The Hiiumaa Museum science and exhibition centre has a permanent exhibition, about life in Kärdla during the period of the woolen factory and also has temporary exhibitions. In addition to the exhibitions, lectures, concerts and salon evenings take place in the building’s main hall.

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.
