The area of Kežmarok was already settled 50 000 years ago. It is proved by the archaeological finds from the early Stone Age up to the period of the Slavonic settling. The Slavonic finds found in the Kežmarok area date back to the 9th and 10th century.

Kežmarok was established by merging several settlements of the original Slavonic inhabitants with a settlement of German colonists (the settlements are first mentioned in 1251), who came after the Tartars´ invasion.
