Druchtag Motte is a classic example of a Norman motte, or castle mound. The history of motte is practically unknown. There are no indications of an encircling bailey as you might expect of a typical Norman fortification, but from the nature of the site, it seems reasonable to suggest a 12th-century date. It appears that the motte was never converted to a stone castle, as many Norman fortifications were.
Druchtag Motte may have been erected by an Anglo-Norman lord, but it could also have been built by a local Celtic lord who was imitating the style of the incoming Normans. Druchtag falls within the Barony of Mochrum of Druchtag which was held for many years by the McCulloch clan. It is one of over 60 similar mottes throughout Dumfries and Galloway and was one of the first historic sites in Scotland to be placed under government care.
The motte is extremely easy to find. It lies immediately north of Mochrum village on a minor road off the A747. There is a small layby next to the site, but the road is narrow and it is perhaps easier to park along the road in the village and walk up the road, a matter of no more than 100 yards.
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.
