In its varied exhibition, the German Horse Museum shows the importance that horses have had for humans over the centuries. As the most important helper in agriculture, transport, mining or war, it was a close, indispensable partner for generations and had a great influence on social development.

No other stallion in the world's riding horse breeds has become as well-known as the Trakehner main sire Tempelwachter (1905-33). His sons and grandsons dominated the state horse breeding in East Prussia. He was cast life-size in bronze in 1932. On the base of the monument in front of Trakehnens Castle it was engraved: “To the German horse”. Temple keeper was a symbol of his stud farm, his country and German horse breeding, an international term. Today his name can still be found in the ancestry of important breeding and performance horses, especially in Germany, Denmark, Holland, Canada, Poland, Russia, Sweden and the USA.
