Based on the contour lines, this is not a peak

This is a flat area in a campsite, reverted again

Reverting bogus summit

Please tell me you are not serious and that this is some sort of a joke.
The BT tower is in no way natural or a peak. In OSM we map what we see, this is a building.
I am reverting this edit.

Hi, please could you keep your changesets to sensible areas. Large area changesets such as this makes it very difficult for local mappers to spot changes in their area.
Please save and start a new changeset before moving to another area.
Cheers Phil

What evidence is there that this is a peak in an OSM sense? From historic OSM maps this appears to be no more than a spot height.
It is not good practice to repurpose the island tag, and its wikipedia tag.

What is the source of this name? From old OS maps it appears to be the name of somewhere nearby, not the peak.

It may be more accurate to map it as the triangulation point as the area appears rather flat and not really a distinctive peak.

Hi, what is the souce of this name?

On old OS maps it appears to the be name of a nearby lake. It was probably correct previously as an un-named viewpoint.

Hi, welcome to OSM. Thank you for your edit, however you have created a duplicate object as the school is already mapped as an area (the preferred method for large objects.
Your edit suggests that the name has changed? If that is correct then we should delete your node and correct the name on the exixting object?
Cheers Phil

This is also not a park in OSM terms, I am reverting this

Hi, welcome to OSM.
In OSM tagging terms this is a recreation ground, which is how it was mapped. To tag it as a park is misleading. Please do not change existing tagging unless it is clearly wrong.
I am reverting this edit.

Thank you for your additions, however the syntax should be name:cy and name:en rather than name_cy and name_en.

Bore da, heathland is a bit unlikely in this part of the world. What is your source?

Fiction reverted

Reverted

Transferred to trig point

Reverted, not really a peak

Reverted, this is an arable field. Nothing on historic OS mapping

Reverted, this is an arable field

This is ridiculous, a peak on the side of a mountain?
