In the 1242 Battle of Lake Peipus, also called the Battle on the Ice, the defeat of the Teutonic knights by Prince Alexander Nevsky marked the end of the Baltic Crusades, which attempted to assert Catholic dominion over the still-pagan or Orthodox Eastern Europe. Campers immerse themselves in the history of the Baltic Crusades through role-playing, games, and creating a medieval battle diorama with miniature handpainted soldiers. A trip the Walters Art Museum’s medieval European collection sparks their imaginations and creativity.
