Trin Castle and fortifications

Few people know that the Crap Sogn Barcazi – the immense rock that rises proudly above Trin Mulin with a church standing on its plateau – conceals military fortifications within it. The fortifications are linked to another fortress at Crap Pign, by an underground staircase with more than 300 steps. The imposing fortress, surrounded by several well-camouflaged bunkers, was the last bastion of the Réduit.


There are twice-monthly guided tours around the Trin fortifications:
