Grójec

In later centuries Grójec lived by trade rather than rule. Duke Janusz I of Warsaw granted it town rights in 1419, and after Mazovia passed to the Crown it became a royal town and, from 1526, the seat of a county in the land of Czersk. Its fortune lay on the road between Warsaw and Kraków, one of the busiest trade routes in Poland, which ran through the town, until the Swedes laid it waste in 1656, during the Deluge.
