Only the open wooden gates and a few narrow windows suggest that the heap of rocks ahead was once something more. A small gatehouse to one side still stands intact, though it seems in danger of collapse beneath the light covering of moss on its stones.
Fort Estazano hunkers atop a small, flat hill, tall enough to give a fine view of the surrounding countryside from the gatehouse.
You can enter the fort either through the open gate or by climbing the crumbling walls.
