In the 5th century BC, during the Hallstatt period, a circular hillfort with two rows of massive stone walls was built at the top of Great Blaník; its remnants are still visible around the summit.

The main legend about knights arose probably in the 15th century among the common people on the basis of an event, when the enemy army was defeated in a miraculous way at the southeastern foothill of Blaník, near the village of Býkovice.

As soon as the Czech country will be in its deepest distress, a rock shall open up in the mountain, the knights inside wake up from a deep sleep, and will set off against the enemies.

From the Great Blaník Wenceslaus is accompanied by his soldiers and comes on a white horse to Louňovice pod Blaníkem square, where the celebrations are held.
