Gusanagyugh is located in the Ani region of Shirak Province. Within Gusanagyugh's territory stand four fortresses: "Arkayablur," "Berd Yal," a 10th–12th-century fortress inside the village itself, and the "Shah Tapa" open-site fortress.
"Arkayablur" lies about 0.5 km southwest of Gusanagyugh and dates to the 2nd–1st millennia BC. It stands on a small, oval-shaped rise, at whose summit sections of a wall over two meters high, built of fieldstones without mortar, have been preserved. The fortress's entrance was on the western side, and remains of a chapel have also survived on the site.
"Berd Yal" lies about 1.5 km south of the village and likewise dates to the 2nd–1st millennia BC. The outer faces of its walls are built of large, undressed fieldstones, with a core of smaller stones, entirely without mortar; the walls reach a thickness of 4–5 meters.
The fortress preserved in the center of Gusanagyugh dates to the 10th–12th centuries, and locals have called it "Ghula." The structure had a rectangular plan, three floors, and wooden inter-floor ceilings; the surviving walls reach about 7 meters in height.
The fourth fortress lies about 1 km south of Gusanagyugh, at the site called "Shah Tapa," and dates to the 2nd–1st millennia BC. According to Toramanyan's description, the rise was about 8 m high, its summit about 122 m long and 47–48 m wide, with the upper enclosing wall about 2.7 m thick.
