The stone manor house was built in 1782–1789. The last wave of construction was completed by 1810. Count Carl Friedrich von Toll made major alterations in the mid-1820s, following the example of St. Petersburg. The manor still looks like this.

In 1919, the manor was nationalised. Today, the Koeru Secondary School operates there.
