For as long as societies have existed, we humans have constantly pushed the limits on designing and creating newer, bigger, and better buildings.

But for all the jaw-dropping structures that we've actually erected, there are some mega-projects that, for better or worse, never made it off the drawing board.

From colossal pyramids containing entire cemeteries to a skyscraper that literally hangs from space,

here are the most insane megaprojects that were never built.

You're listening. You're listening to you. projects that were never built.

The Great Pyramids of Giza are arguably the most famous pyramid-shaped constructs in the world. However, 200 years ago, another prodigious pyramid was almost erected that would have rivaled their fame.

By the 1820s, London was the most populated city in the world, so, unsurprisingly, space was tight.

So tight, in fact, that even those in the city's burial grounds felt the squeeze.

With coffins often being laid on top of one another engraved some 20 feet deep.

Eventually, it got so bad that old cadavers were being discarded from their resting places just to make room for fresh ones.

So, in the 1820s, architect Thomas Wilson proposed a sizable solution to solve London's corpse conundrum.

He wanted to build the Metropolitan Sepulchre, better known as the London Death Pyramid.

A 94-story high granite pyramid burial structure on Primrose Hill in North London.

And all the bizarre building would have stretched almost a thousand feet into the London skyline,

making it around the same height as the Shard, one of the tallest buildings in the UK today.

Ugly as this stony cemetery would have looked, it definitely would have provided some respite to London's burial issue,

because this thing would have housed up to 5 million bodies.

The idea was to fill up the pyramid with around 40,000 because this thing would have housed up to 5 million bodies.

The idea was to fill up the pyramid with around 40,000 bodies annually, meaning,

in just 125 years London would be left with a defunct death pyramid full of corpses.

Charming.

On top of that, the heightened opaque material of this superstructure would have undoubtedly blocked out sunlight for anyone unlucky enough to live near it.
