The traditional summer excursion of the group took place June 26th to visit Sigüenza, the old Castilian city which origin goes back to the Celtiberian Segontia. After the 2 hours walk by the pines and under a suffocating sun to the nearby Natural Park, we had a comforting lunch. It was followed by the cultural visit to the medieval Castle and the gothic Cathedral that hosts the famous tomb of the Doncel.
