Glehn Castle

Glehn Castle, also known as Mustamäe Manor, is a historic residence located on the hillside of the Nõmme district in Tallinn, Estonia. Designed and established by Nikolai von Glehn on land formerly part of his Jälgimäe Manor, the castle was completed in 1886 to serve as his new home. The site reflects the personal vision of its creator, featuring a surrounding park filled with unique structures designed by Glehn himself. Notable additions include a palm house built between 1900 and 1910, an observatory tower constructed in 1910, and distinctive sculptures such as Kalevipoeg and a Crocodile, both installed in 1908. These elements combine to create a distinctive architectural ensemble that blends residential luxury with whimsical landscape design.

The castle experienced a turbulent period after Glehn emigrated to Germany in 1918, during which the property was looted and fell into significant decline. It remained in a state of disrepair until restoration efforts began in the 1960s. Following extensive renovation work, the palace was officially inaugurated on March 24, 1977. Today, the building stands restored and serves as a cultural landmark within Tallinn. The observatory tower continues to function as the Tallinn Observatory, maintaining its original scientific purpose. The estate's rich history and unique appearance have also made it a popular location for film production, most notably serving as a shooting location for the 1981 Soviet adaptation of The Hound of the Baskervilles.
