Glehn Castle is a charming historic manor located in the picturesque Nõmme district, which is today part of the city of Tallinn. Built in 1886 according to the design of Baron Nikolai von Glehn, the castle is a striking example of the Neo-Gothic style. The strict lines of gray stone, crenelated parapets, and elegant towers create an atmosphere of medieval romance right in the middle of a pine forest.

This architectural complex, officially known as Mustamäe Manor, is famous for more than just its main building. On its grounds in Estonia, you can find unique structures: a futuristic observatory (for its time), the ruins of a palm house, and colossal concrete sculptures. Today, the castle is managed by Tallinn University of Technology and serves as a venue for ceremonial events and cultural gatherings.
The surrounding forest park is a favorite spot for walks. Away from the hustle and bustle of the city center, it is an ideal place for those seeking solitude and wanting to see an unusual side of Estonian architecture, where one man's fantasy intertwines with the rugged beauty of northern nature.
