The main church of Surp Stepanos was built in 1000 by Queen Shahandukht, ruler of the lands of Syunik. Prior to the construction of the church stood a shrine to Saint Grigor Lusavorich. Four sacristies were placed at the southeastern end of S. Stepanos.
The adjoining church of Surp Karapet was constructed in 1006-1007 by Queen Shahandukht's son Sevada. The structure has a triple-arched portico at the front façade. A circular drum and a recently reconstructed dome rest above the cruciform plan of the church.
Vorotnavank was destroyed multiple times by foreign invasions as well as an earthquake in 1931 during which S. Karapet's dome collapsed. In 1104 Seljuk-Turksattacked the monastery and the nearby fortress of Vorotnaberd (3 km southeast). Ivane Zakaryan liberated them and gave control of Vorotnavank and Vorotnaberd toLiparit Orbelian of the Orbelyan family. The monastery was repaired and made funcionable during this time. Other foreign invasions included the Mongol-Tatars(1236?) and later Timur Lenk in 1386. An underground passageway was connected to the fortress of Vorotnaberd, and was used during sieges by invading armies. Reconstruction efforts have been underway since 1980 and are nearly complete.
