Tarasp Castle was probably built in the 11th century or possibly as early as the 10th century. The name comes from terra aspera or wild earth, which may refer to the newly lands in the Inn river valley. They had adopted the name of the castle by 1089 when Ulrich von Tarasp was mentioned in a papal mandate to the Bishop of Chur. Around the same time the family founded Scuol Monastery, which later moved to Marienberg Abbey, as part of their program to carve out a barony in the formerly uninhabited high alpine valley. At this time the castle consisted of a ring wall and a chapel with a bell tower that also served as a watch tower.
In 1160 Ulrich II donated his portion of the castle to the Bishop of Chur. However, his nephew and co-owner Gerhard, with the support of the Count of Tyrol, seized the castle and drove out the bishop's troops in 1163. The bishop, together with Ulrich von Tarasp and his cousin Egino von Matsch, besieged the castle and eventually forced Gerhard to compromise. The castle became the bishop's, but Gerhard and his descendants would hold the castle as their fief. If Gerhard died without an heir, the castle would revert to the bishop. In 1170 Gerhard died a violent death, followed by the last male heir, Ulrich, in 1177. The castle passed to the bishop while the Matsch family inherited the Abbey. In 1200 the bishop appointed the Reichenberg family as his vogt or representative in Tarasp Castle. In 1239 Swiker von Reichenberg, ignoring the bishop's claim, sold the castle to the castle to Albert of Tyrol. Beginning in 1273 the Matsch family received Tarasp as vassals of Tyrol.
The Matsch family held Tarasp for about a century and a half. When the lands of the Counts of Tyrol were inherited by the Dukes of Austria, the Matschs became Habsburg vassals. In 1422 Frederick VII of Toggenburginherited Tarasp through his wife Elisabeth von Matsch, but when he died in 1436, it returned to the Matsch family. In 1464 Ulrich IX von Matsch sold the castle to Sigmund of Austria, which triggered an uprising in Lower Engadine. While the Austrians were able to retain control over the region, relations remained tense between the castle and the locals. When the Protestant Reformation was adopted in Engadine the situation became worse. In 1548 and again in 1578 Protestant locals attacked and attempted to capture the castle. Despite additional fortifications, in 1612 they successfully stormed and burned Tarasp. A lightning strike in 1625 set the castle on fire again and killed the daughter of the Austrian representative in the castle.
Over the next centuries, Tarasp was occupied by a number of administrators, but remained under Austrian control. By the 18th century Tarasp was the only Austrian territory in Switzerland. Throughout this period, the castle was often expanded and renovated to its present appearance. After the French invasion of Switzerland and the creation of the Helvetic Republic, in 1803 the castle was taken from the Austrians and given to the Republic. A few months later, when the Republic collapsed, the castle was transferred to the newly created Canton of Graubünden. After about 1815 the castle was abandoned and rapidly fell into ruin.
Initially the Canton planned to turn the castle into a prison, but eventually gave up the idea as too expensive and began looking for a buyer. The von Planta family bought it in 1856, began repairing it and replaced the damaged roof. In 1900 it was purchased by Dr. Lingner of Dresden, who restored the castle for a decade from 1906 to 1916. After his death, Grand Duke Ernest Ludwig von Hessen inherited the castle from Lingner. It was turned into a museum in 1919. In 2004 the von Hessen family announced that they wanted to sell the castle. In 2008 the municipality of Tarasp agreed to investigate purchasing it and converting it into a cultural and tourist attraction. In 2010 the Fundaziun Chastè da Tarasp was created to seek funding and administer the castle after it was purchased. After the Foundation struggled to raise funding, in 2015 Swiss artist Not Vital announced that he would purchase the castle. In March 2016 Not Vital acquired the castle.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.
