Soroca Fortress is the only fortress built in the 15th century in Moldova, which has been preserved til now.

Tighina Fortress, located on the bank of the Dinester River was one of the most powerful fortresses of Moldova. During the '70-'80s of the 16th century, Tighina was incorporated to the Principality of Moldova. Tighina becomes an important point on the Moldovan Trade Route linking Western Europe with Orient through the Danube ford from Isaccea, Byzantine regions from the right of the Danube with Caffa, Genoese colony in the Crimea. 

The Fortress of Orhei is one of the most important fortifications in Moldova's eastern border. It dates back to the 60’s of the fifteenth century, becoming then the residence of the chief magistrate of Orhei. The architecture of the building is similar to the typical Moldovan houses of that time. Currently, only the foundation of the building was preserved - as a symbol of Old Orhei.
