Mud from the Marble Arch mound will be used to rebuild Hadrian's Wall as part of Tory 'levelling up' plans, it can be exclusively revealed by the Mirror.
Tourism experts say the Twitter storm that greeted the west London rubbish heap will soon be replicated up north.
"As we all know, Twitter mentions equals eyeballs and by that metric the Marble Arch mound has been a huge success", one said.
Londoners were distraught when the £6m mound started to be demolished earlier this year after it was such a storming success.
Thousands visited the grassy knoll and were amazed by the views it offered of several nearby Pret a Manger.
Tory MP and London tourism minister Mike Wrap said: "I know Londoners will be bitterly disappointed to be losing this iconic temporary structure that has been compared to the Eiffel Tower.
"Sadly, unlike the inferior Eiffel, this one has to come down and the opportunity to rebuild Hadrian's Wall and level up the north could not be missed.
"The mound is simply too good for London to hog it to itself.
"Hadrian's Wall has been incomplete for too long and, frankly, is an eyesore whereas the mound has lit up the London skies."
The ambitious project is estimated to cost £10bn and take three months but will actually cost £720bn and probably never be finished.
Mr Wrap said Northerners would be thrilled with the scheme and denied suggestions that it was an attempt to placate red wall voters with 'London castoffs'.
"They're always talking about how expensive it is down here, well this is free of charge!
"It's time to spread the wealth and culture of London and how better to do this than by 'spreading' the mound up north."
Tourism chiefs said the fact that Hadrian's Wall was a UNESCO World Heritage Site was "not important" with one quipping to the Mirror: "Can't can't we just have a referendum on UNE-xit?'.
London resident Victoria Applecross said: "Seeing the mound go was a bitter blow but I'll sleep easier knowing it's going to a good home and a good use.
"Maybe they should rename the wall? Hadrian died ages ago anyway and no one knows who he is these days."
A Northern Labour MP told the Mirror he would 'lie down in front of the lorries' to stop them driving north with sections of the mound.
An independent assessment of the project estimated the work would take until April 1 2099.
