Tõstamaa Manor was first mentioned in 1553 as Testama, when it belonged to the Bishop of Ösel–Wiek. Lated the owners have been the Kursells, Helmersens and Staël von Holsteins. The Early-Classical two-storey main building was built in 1804. During a renovation in 1997, several original painted ceilings were uncovered. The manor was dispossessed in 1919 and since 1921 a local school (Tõstamaa Keskkool) is operating in the main building. The most famous inhabitant of the manor is probably Alexander von Staël-Holstein, who grew up and spent his childhood at the manor.
References:Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
