The history of Puurmani Manor (in German: Schloß Talkhof) dates back to the Middle Ages when a castle of the Order was located here. It was a residence of the Vogt of the Order. The castle was built to protect the crossing point of River Pedja and the main road between Tartu and Tallinn.
Later the place of the former castle was turned into a manor. The Estonian name of the estate stems from the Buhrmeister family, who were the owners in the Swedish times after having been given the manor in 1645 by Queen Kristina. By 1919, the year of expropriation, the estate was owned by the aristocratic von Manteuffel family.
The present neo-Renaissance styled main building was built by Ernst von Manteuffel in 1860’s. One of the palace's frontal corners is emphasized by a five-floored octagonal tower. Both the tower and the facade of the building are richly decorated. In the interior design Neo-Renaissance is combined with Neo-Baroque.
The Puurmani park and estate complex is under national protection. More than 50 species of trees and bushes can be found in the well organized park, which is divided into two parts. The front of the manor is arranged symmetrically according to the French style. The part behind the building exhibits the English style with its informal landscape gardening. Linden alleys and red brick fences also enhance the beauty of the park.
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.
