Mutlow Hill is a mid Bronze age roundbarrow next to the impressive Saxon Fleam Dyke. It was reused by the Romans for a temple site. A gold coach is reputedly buried inside. An 1852 source put it that this "is, or should I rather now say has, been implicitly believed among the labouring classes thereabouts for many years."(!)*
'Mutlow Hill' might come from 'Moot Low' / 'Gemot hlaw' - a Saxon meeting mound. It is at the boundary of three hundreds.
