This gnome-fronted, surreally ordinary house displays a chaotic hotchpotch of WWI helmets, shoes, guns and harrowing photos, some in antiquated wooden stereoscopic viewers. The main attempted justification for the hefty entrance fee is a string of ‘original trenches’ in the woodland garden and the cross-pinned relic of a bombarded tree. It’s between Sanctuary Wood British Cemetery and the Canadian Hill 62 memorial, 2km down a dead-end lane from Hooge bus stop.
