Aparan Basilica

Aparan Basilica, formally the Holy Cross Church and sometimes called the Kasagh Basilica, is an early medieval church in Aparan dated by scholars to the fourth or fifth century. It stood originally within the grounds of an Arsacid (Arshakuni) dynasty royal palace, making it one of the few surviving church buildings tied directly to that dynasty's residences.

The church was partly restored in 1877. No other structures from the palace complex are noted as still standing.

The church stands in the town of Aparan, Aragatsotn region, about 48 km north-northwest of Yerevan as the crow flies.
