I walked through Drymere, near Swaffham, yesterday and I have to say, lovely as it was, there wasn’t an abundance of facilities. The Concise Oxford Dictionary Of English Placenames also doesn’t list Drymere as a location, the first such village I’ve come across that isn’t listed.
And, this is probably why, the map from 100 years ago shows there’s no such place as Drymere. It wasn’t a village, there was just a pit which had the name that just means a ‘dry hole’. So, a handy way of naming a location where there are a few houses, but it seems there’s not much heritage beyond that.
