Šarišský hrad in Veľký Šariš

You're standing at the ruins of Šariš Castle, high above the little town of Veľký Šariš in eastern Slovakia. You're about 570 metres above sea level here, on top of a cone-shaped hill. Have a look around. The summit isn't a narrow peak but a wide plateau. Plenty of room for a big castle, and that's exactly what this was: one of the oldest and largest castles in Slovakia.
