An excellent example of German fortress engineering. It was built using the continuous pour method and the walls and ceilings consist of 12ft thick reinforced concrete. There are 7 storeys and the whole thing took just 7 weeks to construct.

Designed by John Wilson who also designed town market square, St. James and Elizabeth College in St. Peter Port. It has the tallest steeple in Guernsey and is used as a sea mark by sailers.

Unusually the church is built on a slope so couples getting married here really do walk ‘up’ the aisle! Note the stained glass window with St. Peter wearing a Guernsey!

Largest structural reminder of the German Occupation. The tunnels cover 7,000 square meters and were constructed by slave labourers who excavated nearly 30,000 cubic meters of rock sometimes using hand tools and their bare hands. The space is somber and cavernous with a haunted eerie feel. Take an extra jumper as it gets cold in the tunnels.
