Glehn's Castle, erected in 1886 on a scenic hillside in Tallinn's Nõmme district, exemplifies striking Neo-Gothic architecture designed by Baron Nikolai von Glehn. The castle complex includes a surrounding park with a palm house, observatory tower, and sculptures crafted by Glehn himself. After being reduced to ruins by the mid-20th century, the castle was restored between 1966 and 1977 under the leadership of the Academic Male Choir of Tallinn University of Technology. Today managed by TalTech, it serves as a venue for ceremonial events and cultural gatherings.
