The first fort in Isein was built by bishop Atto of Freising in 784-811 AD. The current Burgrain castle dates from 1200s, when the lords of Burgrain built a four-winged building with keep and moat. The extensive additions and renovation was made in the 15th century by bishop Nicodemus.
After the secularization in 1804 Burgrain castle has been in possession of several owners. In 1906 it was converted into a home for blinds. Since 1919 it has been a private residence.
The castle church dates from 1719 and is richly decorated with rococo plasterwork.

Doune Castle was originally built in the thirteenth century, then probably damaged in the Scottish Wars of Independence, before being rebuilt in its present form in the late 14th century by Robert Stewart, Duke of Albany (c. 1340–1420), the son of King Robert II of Scots, and Regent of Scotland from 1388 until his death. Duke Robert"s stronghold has survived relatively unchanged and complete, and the whole castle was traditionally thought of as the result of a single period of construction at this time. The castle passed to the crown in 1425, when Albany"s son was executed, and was used as a royal hunting lodge and dower house.
In the later 16th century, Doune became the property of the Earls of Moray. The castle saw military action during the Wars of the Three Kingdoms and Glencairn"s rising in the mid-17th century, and during the Jacobite risings of the late 17th century and 18th century.
