Milliner’s Cottage is on Castle Hill on the original site of the city of Cambridge and now a mile or so north of the present-day centre of the city.
There is a castle, but it is just a grassy mound next to the car park of the Council offices at Shire Hall, a hundred yards further up the hill.
I googled ‘Milliner’s Cottage’ and according to the estate agent’s details from 2013 that I googled, (is everything kept forever, online?) Milliner’s Cottage is a Grade II listed Georgian property created out of two cottages, one of which was indeed a milliners’ cottage.
So it is a cottage, a home. It is not a business. And that being so, I think it is odd that there are hats in the window.
