Old Orhei contains traces of different civilizations, including the remnants of earthen and wooden fortresses of Geto–Dacian fortress (6th–1st centuries B.C.), the Golden Horde fort Shehr al-Jedid (or Yangi-Shehr) (14th century), a Moldavian fort dating from the 14th-16th centuries, an Orthodox monastery (c. 14th century), and the Moldavian town of Orhei from the 14th–16th centuries.

The Orthodox monastery is still inhabited by a handful of Orthodox monks, who maintain the church at the top of the hill. The caves are still functional as chapels. The caves contain an array of historical artifacts and Old Church Slavonic inscriptions dating from the 1690s, which testify that the Hajduk took shelter in the caves, hiding from the Ottoman Empire.
