Steiner Tor is a-preserved gate, originally built in the late 15th century but refashioned in the Baroque style in the city of Krems an der Donau, in the Wachau valley. It is considered the symbol of the city. Until the last third of the 19th century, the city of Krems was surrounded by a wall. This was systematically razed, and three gates were also removed. From 2005, celebrating the 700-year anniversary of the city rights, the Steiner Tor was restored as much to its original as possible.
Outside the portal are towers flanking both sides, which, like the lower floor of the gate, date from the late Middle Ages. On the right of the archway is a small stone coat of arms mentioning Emperor Friedrich III, and the year 1480 in Roman numerals. This is believed to date the restoration of the fortifications that had become necessary because of the destruction wrought by Hungarian troops in 1477. The tower building dates from much more recently, and dates to the Baroque period during the reign of Maria Theresa, 1756. Outside the gate, the Steiner Tor was originally threatened by flooding from the Danube. On the inner side of the stone door is a mounted memorial which commemorates such a disaster in 1573.References:
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.
