Talk:List of highest points in London

message: Might I propose The Ridge, Orpington - according to the contour mapping on openstreetmap.org, many of the properties in this street are around 110m above sea level.  — Preceding unsigned comment added by 81.96.3.228 (talk) 14:33, 1 January 2013 (UTC)

thread_title: Suggested additional entries/deletions

message: Is this a work in progress or definitive list? I would add Muswell Hill. No spot-height above 100m on Explorer maps, but Explorer 173 has a closed 100m contour around the top and Fortis Green, and unlabelled but presumably 105m contour just behind the library, (). I'll dig out my old 6" paper map and see if it has some better-placed spot heights in shillings.
: Confirmed: The old OS 1:10,560 sheet TQ28NE dated 1968 has spot heights at all the main road junctions. These include  at the roundabout at the top of the hill (),  at the top of St James's Lane () and  at the top of Fortis Green (). Hey is it just me or does ({convert}) make 340ft lower than 331 ft?

thread_title: Within M25

message: When checking the heights of the hills in the source quoted I noticed that they were given in metres first. Therefore it seems appropriate to  follow this in the article. Putting them the other way round could lead to rounding errors, and if a hill has been resurveyed and found to be different, this might be missed if the list is feet first.

replies: text: When making the changes I noticed that some of the high points were not properly supported by the two sources cited (or where a cited source gave another value). I have placed citation notices where this occurred. Michael Glass (talk) 11:15, 19 March 2010 (UTC)
thread_title:  Heights of hills per source 

message: These peaks I note are nearly all technically part of London since the creation of Greater London. What about the City and Westminster?  In the City there is a plaque at Panyer Alley which bears rhyme: 'When ye have sought the cittye round/yet still is this the highest ground' but a Ward Lock 1928 guide to London says 'that honour belongs more to Cornhill'. Some discussion would make good comparison.Cloptonson (talk) 11:25, 14 August 2020 (UTC)
thread_title: What about natural highest points in the City and Westminster?

message: An unnamed hill in Harrow-on-Hill is claimed to be the only isolated peak with the rest being parts of ridges. A recent (now reverted) edit suggested this honour belongs to the higher Stanmore Hill. The hill next to Church Hill, Harrow is indeed isolated. Stanmore Hill, however, is on a ridge that includes Harrow Weald Common, Pinner Hill and Woodcock Hill. Apologies for doing original research using OS maps.
By the way, St Mary's church is built on the summit of the unnamed hill. Should we use that as the hill's name? OrewaTel (talk) 21:40, 6 January 2022 (UTC)
