Tower between the trees

Tower between the trees is a castle, fort or tower in Powys, Wales. Perhaps it stood as a watchtower above the valley, its stones catching the last light while keeping a quiet vigil over the land. Maybe it was built to guard a crossing or a boundary, its height giving whoever climbed it a clear view of the surrounding fields and forests. Imagine it still standing, its shape simplified by distance but its purpose preserved in the memory of the place.
