The archipelago

Sörmlands archipelago is more than 10 000 years old, has a sixty kilometer long coastline and consists of Trosa, Nyköping and Oxelösunds municipality. There is about 2 800 islands. Sörmlands archipelago is not as exploited as many other places along the Swedish coastline. Large areas are also nature reserves.

Island “Grytan”

Around the island of Grytan, east of Kråmö, there are many exciting stories. Here it is said to have been liquor smuggling and an advanced hiding game with the customs service, primarily in the alcohol restrictive 1930’s. Grytan (“the kettle”) has probably got its name from the giant holes made by the ice sheet achieved in the flat rocks.

Island “Korpen”

The 23 meter high cliffwall rises dramatically from the sea. This is the place for a very local test of manhood. It is said that you have to jump from there to being viewed as a real man in Trosa. However, it is dangerous and not recommended.

Island “Öja”, Landsort

The island Öja has a wonderful view. This is where Stockholm and Trosa archipelagos meet. The island also has the oldest lighthouse, Landsort. Since the 1660s it has shone continuously to show the safe path up towards Dalarö and Stockholm. The present lighthouse dates from 1678 and is the archipelago’s strongest, with a nominal range of 18 nautical miles. Landsort is probably also the oldest pilotstation where ships on order of Gustav Vasa have been piloting assistance since 1535. Landsort was, for many years, an active community with school, business and military activities but is now mostly an island with summer visitors and tourists. The year-round residents is estimated to be somewhere between 10 and 20 people. There are three harbours on Öja; Norrhamn (Northern harbour), Östhamn (East harbour) and Västhamn (West harbour). A lovely walk leads around the island and up to the lighthouse. Eider ducks and other birdscan can be seen here in the spring and autumn and there is a bird observatory on the island. The pest Cemetery from 1710, when almost half the island’s population died, is worth seeing, as well as the archipelago’s largest pothole, 4 feet deep and 3 feet in diameter, located northeast of Norrviken.

Christmas Eve lighthouse

Christmas Eve lighthouse on the island of Bokö-Oxnö is a nature reserve. The island is relatively difficult to reach, but it can be at Skonötudden on the east side. The lighthouse is located on the north side. The lighthouse is said to have received its name when a ship was wrecked here during a snowstorm on Christmas Eve. Opposite the Christmas Eve lighthouse you can see Högholmen, also known as Smuggler mountain. Below the hill there is a deep and good anchorage where cargoboats in the old days were waiting for the right wind to sail through Boköströmmen. The site was also used for boats that had smuggeled goods on board. Smuggler mountain with its caves was a perfect hideaway.

 Island Kråmö

The idyllic island Kråmö lies a comfortable boat trip from Trosa. Twelve cottages of various sizes are available for rent on the island. They do not have electricity or running water. The harbour is very idyllic and a wonderful place for swimming. Sauna bathing, fishing and berrypicking can be done. There is also a big grass area and barbecue places.

Kråmö island, with the old island farm which has roots in the 1600s, was formerly part of the estate Tureholm. In the 1940s, Kråmö was bought of a dairy owner who built the cottages for their workers. Nowadays this summer idyll is owned by Trosa municipality. There is a café that sells ice-cream and simpler foods at the pier.

There are countless stories about the legendary Tärken who lived on Kråmö for 52 years. Einar Tärk and his wife Hilja were the last residents of the island, but in 2003 they moved to Trosa. Several generations of children in Trosa remember Hilja who worked in the school canteen. Einar, who fled Estonia in a rowboat in the 1940s built solid fishing boats at Kråmö. The biggest boat he built is still there. Nowadays there is a museum on Kråmö. It shows, apart from archipelago subjects, a part of Tärkens life work. Tärk has also given its name to the treacherous stone collection north of Kråmö between Brännskär and Högholmen. For a long time it was not marked on the chart. It is said that Tärken stood on his mountain and looked for boats that hit the stones. When someone got caught, he went out with the fishing boat and pulled off the boat – against fair compensation of course. Not until he himself got stuck there and a neighbor had to come and pull him off for a fee, of course, came “Tärks grund” to be marked on the chart.

Island Askö

The over 8 km long Asko has large sections of forest, including very old pine trees. There is also an archaic agricultural landscape that still is grazed by sheep and cows. Rare orchid flowers grow in the meadows and in the varied environment of the archipelago you can see diffrent kind of rare insects. Askö has relatively few natural harbors but Storsand and Lillsand are popular sandy beaches where you can get to by boat. On sunny summer days it is often catch rides between the boats out here to get the best seats!

Askö Laboratory was built on the north of Askö in 1961, it coordinates Swedish marine research and environmental monitoring. The laboratory is one of Stockholm University’s marine research center and is located in one of the least affected coastal areas along the entire east coast, which is also one of the most well-studied marine areas in the world. It conducts research and training throughout the year in the marine sector. The Askö area works since the 1970s as a reference area for observation and has great international significance.
