The site was investigated in 1975/76. The fortress-like main building is divided into two rooms, one large and the other small, both with low benches. Both rooms contained various paintings and inscriptions on the walls and on two large water-jars ("pithoi"), one found in each room. The paintings on the pithoi show various animals, stylised trees, and human figures, some of which may represent gods. They appear to have been done over a fairly considerable period and by several different artists, and do not form coherent scenes. The iconography is entirely Syrian/Phoenician and lacks any connection to the Egyptian models commonly found in Palestinian art.
The inscriptions are in a mix of Phoenician and Hebrew script. Many are religious in nature, invoking the gods Yahweh, El and Baal, and two include the phrases "Yahweh of Samaria and his Asherah" and "Yahweh of Teman and his Asherah."  There is general agreement that Yahweh is being invoked as a god in connection with Samaria (capital of the kingdom of Israel) and Teman (in Edom); this suggests that Yahweh had a temple in Samaria, and raises a question over the relationship between Yahweh, the Israelite god, and Kaus, the national god of Edom. The "Asherah" is most likely a cultic object, although the relationship of this object (a stylised tree perhaps) to Yahweh and to the goddess Asherah, consort of the god El, is unclear.
