The Knight's Palace is a green palace, a very interesting building, with a strong European history. It is currently the main part of the Estonian Art Museum, which mainly displays the works of Estonian artists. It is worth visiting.
Right behind the Cathedral of Alexander Nevsky, at first glance, I only think the green exterior wall is quite interesting. It looks a bit dilapidated as a whole. It was dark at the time, and I thought it might be a building of some kind of unit. Thinking of it turned out to be the Palace of the Knights, Tallinn is really full of attractions and history.
The color of the exterior wall looks very bright.
One of Tallinn's relatively partial attractions, but the scale of the building is quite large, and it is also very beautiful, it is worth visiting, just on the Toompea.
