Olsztyn near Częstochowa is known primarily for the ruins of the once mighty castle - "Eagle's Nest" from the time of Casmir the Great. In this town of the Polish Jura there are other, perhaps less impressive, but also historic buildings. An eighteenth-century wooden granary at the northern foot of the fortress is impressive. It was moved to Olsztyn from the village of Borowno. Today, it houses a smart restaurant.
