The Kasagh Basilica (Քասաղի բազիլիկա),[1] 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.[2] 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.
