'Chinese wall?'

 In Bellinzona three strongholds nearly close the Ticino valley with their huge walls. Since the Gotthardpass route is following that valley towards Italy, who owned these castles controlled a principal traderoute across the Alps. UNESCO added the complex to their list of World Heritage Sites. Photo Paul Smit.
