Eğil Castle
The most important of the castles built for defense within the borders of Eğil is Eğil Castle. Historical sources tell that the castle was built by the Assyrians. The castle was built on a natural rocky ground and surrounded by deep valleys on three sides, and the other side was carved out to create a strategically important structure. It was probably built only as an inner fortress during the Assyrian period, and an outer fortress was added in later periods. The fortress is fortified with walls and bastions, and the outer wall starts right next to the valley and continues along the southern slope.
On the surface of the steep rocky area to the north of the fortress, a relief of an Assyrian king in a rectangular panel obtained by leveling the rocks and a cuneiform inscription that is too faded to be readable today draw attention. The relief is believed to belong to the Assyrian King Salmanassar III (859-824 BC).
