The Kasagh Basilica (Armenian: Քասաղի բազիլիկա) or the Aparan Basilica, formally known as the Holy Cross Church (Սուրբ Խաչ եկեղեցի, Surb Khach yekeghetsi), is an early medieval Armenian church in the town of Aparan in the Aragatsotn Province of Armenia. It is dated by scholars to the fourth or fifth century. It was originally within the grounds of the Arsacid (Arshakuni) dynasty palace. The church was partly restored in 1877.
