The Great Moravia exhibition tells the story of the great man Mojslav around the foundations of the 9th century cemetery church. The story is presented in the form of historical dioramas. These are made up of life-size figures and depict the basic historical moments of Great Moravia, but also present all the life activities of the inhabitants of the 9th century.

The exposition opens with a cinema about the life of the men who stood at the beginning of Slavic writing. It takes us into the environment of the Byzantine Empire of the mid-9th century, introducing us to the situation and the distribution of power in Europe at that time. Its story traces the birth, rise and fall of Great Moravia, as well as the cultural and literary repercussions associated with the Great Moravian Empire.

The originals of the most important archaeological finds that archaeologists and researchers have managed to collect over the decades in this area speak to the visitor as mute witnesses of the past.
