Tingplatz of East Prussia
As they said in Nordenburg (now Krylovo), according to the recollections of residents, it was built on a hillside, between a cemetery and a sports ground. The initiators of the construction were the "fathers of the city". At the same time as the Tingplatz, a monument to German soldiers who died in the First World War was erected. Construction began in 1937, the opening of the monument and the Tingplatz took place in August 1938. Initially, the territory of the complex was covered with pebbles, but then it was paved. The Tingplatz was a unique landmark of Nordenburg and a source of pride for the townspeople in front of the residents of nearby Gerdauen (now Zheleznodorozhny).




The former Tingplatz is currently located in a restricted area north of the Russian-Polish border and cannot be seen without special permission. All that remains of the complex are forested ruins.



Tilsit-Sovetsk can boast not only the easternmost tram in the Third Reich , and not only its famous cheese , but also the largest East Prussian Tingplatz. It was laid in Tilsit on June 10, 1934, at the height of the Nazi fashion for "populism", when significant funds were allocated to promote the unity of the German nation, which has its roots in time immemorial from the ancient Germans. The authors of the project were Berlin architects Franz Böhmer and Georg Petrich. Tingplatz is located in the western part of the city in Jakobsruhe Park, not far from the monument to Queen Louise. The grand opening of the arena took place on April 30, 1935. Tingplatz is well preserved. Now it is called the "Green Theater" and is used for various city events.

















The Tingplatz in Pravdinsk (formerly Friedland) is not mentioned in any source on the subject that I have access to. It may have been built by the residents themselves using voluntary donations in 1935-1936 (or 1937-1938). In any case, it can be seen (or rather, what is left of it) on a hillside in the southern part of Pravdinsk, 100 m southwest of the fork of Druzhbinskoye Highway and 28th Army Street. One can only guess what the Tingplatz in Friedland looked like before the war, since no informative photographs from that time have been found, and in those that exist, it is impossible to discern details.






In general, I would not be surprised if something similar has been preserved in some small towns in the Polish part of the former East Prussia.
In Insterburg (now Chernyakhovsk), according to the design of the already mentioned architects Böhmer and Petrich, it was also planned to build a tingplatz (it should be added that they also developed designs for tingplatz on Mount Annaberg in Silesia and in Halberstadt, which was never built).
The Tingplatz was to be located southwest of the Insterburg stadium, on the left bank of the Angerrap (now Angrappa) river. It is unclear why the project was never implemented.
