Given that Chris Grayling’s plan for a Stonehenge tunnel is teetering on the edge of oblivion (thanks to Brexit, UNESCO, finances, worldwide criticism and his less than perfect organisational skills) it’s possible that Historic England has been rather tone deaf yet again in highlighting Brunel’s marvellous tunnel at this time. Unkind persons will surely make invidious comparisons!
