History of Denmark between 5000 BC - 1701 BC
Even before the Neolithic period hunting people in Denmark had long had contact with the farming societies in central Europe, but only around 3900 BC the hunters began to till the land and keep animals. Wooded areas were cleared, burnt and replaced with fields of arable crops. Cattle, pigs and sheep appeared as domesticated animals. The big change was that people could produce their own food products. Coastal fishing was still good and therefore the farming population continued for a long time to hunt and fish from the old settlements on the coast.
The farmers’ grave monuments in the form of dolmens and passage graves were constructed all over Denmark. They can be seen still in many places in the Danish landscape. Here you can see the splendid polished flint axes and large collections of amber beads which were offered to the gods in hope of a good harvest. You can also see how the Skarpsalling Pot – Denmark’s most attractive pottery vessel from the Neolithic period – is decorated. Or you can learn more about how daggers, such the one from Hindsgavl, and other flint tools were produced.

Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
