Castle Glen is located in Tallinn, in nõmme district on the slope of Mustamae. Around the castle a beautiful Park. Landowner Nikolai von Glen founded the Park on this slope. The castle was built in 1886. For some unknown reason, the Baron was traded fertile land for lake Harku on the slope of Mustamae piny. Such an act from the point of view of the contemporaries of the landowner von Glen seemed almost insane.

This hill was already popular from the mid 19th century as a place for picnics. Apparently, the Baron planned to establish in this place a city, because the project was a town hall, post office, several churches, a racetrack, and even mud baths.

The castle itself was built by the project owner's site. The squire himself was involved in the construction. The main work was done by prisoners at Tallinn prison. Von Glen sometimes, for the sake of aesthetic development, played prisoners clarinet excerpts from Wagner operas. The castle was built in the medieval Gothic style.

Opposite the castle you will notice the ruins of the "palm house", which is the time of WWII Baron was a semi-underground greenhouse. Unfortunately, today the winter garden of the Baron is in a bad shape. Not far from the ruins on the hill is a four-sided obelisk built in honor of the beloved horse of Baron von Glen.

Next, between tall trees stands a huge sculpture, called "Glanowski hell", although, according to the author, a giant sculpture represented the Estonian character Kalevipoeg. The sculpture we see today is a copy, the original was destroyed during the First World war, the wreckage can be seen in several of the AG from the copy.

Far from "Penovskogo hell" is another stone giant, called "crocodile", which according to the plan of the Baron was the life of the dragon. Between the two sculptures you can see a cavity, like a wide ditch. The Baron planned to do here the river, whose source would be the Pääsküla bog. The river was supposed to flow through the Park, and falling down a waterfall from a cliff. However, this venture did not materialize, because sandy soil has soaked up all the water, and the Park remained parched riverbed.

There are still a construction Baron, which survived until our days is the "lookout tower". According to the plan of Baron tower should be high enough so that it could see the Finnish coast. Unfortunately, the background is Glen failed again: the Foundation was too frail, and this idea had to be abandoned. Today this building houses the Observatory. Eccentric Baron von Glen made a lot of attractions in the Park, which, unfortunately, has not survived.
