"Hill" is a relative term of course. Look at Shippea Hill in the fens. Identifiable as a hill only because it's the last place to get inundated when the area floods.

Looking at the old OS maps on the National Library of Scotland site, there is a trig point in that location...?

OS 25 inch 1892-1914, but it's long gone by the time of the 1:1250 of the 1950s

I wonder if someone has looked at the road name "Mill Hill", put 2 + 2 together and got 5 (naming the now absent trig).

In SW1 there's an Emery Hill St, named. not after an incline, but after a person. Regrettably I can't find a way in which Mill Hill is a person.

Strawberry Hill and Hampton Hill are two other raised areas on the Thames floodplain which are now difficult to detect due to the overbuild. But as with Mulcheney down here on the Somerset Levels a major flood may prove their worth (Mulcheney was cut off for 10 weeks in 2014).

If you go SW from Barnes on the Open Street map you can see a Mill Hill marked on Mitcham Common, to the SE of 7 Islands Pond.

It is however an artificial hill being the highest point on an old tip used by Croydon for their rubbish until about the 1960s. It was then covered by clay and landscaped. How it got the name Mill Hill I do not know: there may have been a windmill there.

FWIW, the OSM mapper that added this feature did this 16 yrs ago and claims OS 1:25k as its source. The beauty of OSM is of course you can ask him, through the OSM Query Feature you can find he is "Dan Karran and I’m currently living in Canning Town, London E16. I’ve been involved in mapping the Isle of Man, Stuttgart and London." It links to an email address too...

I did email him, let's see if he connects ;-)

So, Mill Hill SW13 is a very early "brownfield site"...

I see Gary Lineker once gave an address at this walled community. Meanwhile, upgrades to one property include a new contemporary 'crystal-like' conservatory [which] reflects the Gothic form... Wonderful.

I can assure you Mill Hill in Barnes is a hill, it's easy to feel the long gradual climb up Mill Hill Road on a bicycle coming from Station Road.

Looks indeed like an error naming that peak. Dan emailed me saying "Thanks for the heads up :) It looks like I was doing some armchair mapping using an old OS 1:25k map, so hopefully someone can link down where it came from and fix if necessary.
Cheers, Dan"

With the proliferation of mills at one time, I'm surprised there aren't more Mill Hills locally!
As a native of the proper Mill Hill, the existence of a mill was always a bit vague - a bit like the supposed burnt tree at Burnt Oak!

Well at least it looks like you had a nice afternoon out exploring...

The source tag in OpenStreetMap says OS 1:25k map, but I suspect I actually meant the OS 25 inch map. As a previous commenter suggested, it looks like I may have conflated an old trig point location with the nearby locality name of Mill Hill.

It's always good to have more eyes on open data to check mistakes haven't been made, and I think if that was added now, somebody would pick up on it much sooner.

And there's a property on Mill Hill going for £2.25-£2.5m if you're feeling flush.

There's also two areas called Pimlico.

No there aren't.

I live in the area and often walk and cycle past Mill Hill, Barnes. It has always struck me as an interesting study, as the houses are obviously very nice, but roads around it (excluding the main road) and the scrub and untended bushes of Barnes Common that surround it give it slightly shabby feel.

I guess that's shabby chic.

Never heard of the other Mill Hill? Don't you know where all the beautiful Barnacles cluster? A certain ex Match of the Day presenter lives just off that road.

I don't often see a reference to Muchelney anywhere. I only know of it because it was the birthplace of a Great-Grandfather.

I offer you a wood called Mill Hill to investigate (or not). It's in Farnborough (Bromley) off Tye Lane
