[citation needed] It is known for its well-preserved stronghold, established by the Moldavian Prince Stephen the Great (Romanian: Ştefan cel Mare) in 1499.

Between 1543 and 1546 under the rule of Petru Rareş, the fortress was rebuilt in stone as a perfect circle with five bastions situated at equal distances.

During the Great Turkish War, John Sobieski's forces successfully defended the fortress against the Ottomans.

This observation conveys the idea that the fort was perhaps built by experts from Western Europe or Transylvanian people who traveled in Western Europe and brought architectural ideas back to Moldova : The entire building has a diameter of 30 meters, and 4 meters for each tower.

The space saved at the upper level allowed the garrison to pray in a small chapel.
