Abandoned Engineering - what’s this building

[DSLiverpool]

Great series on Yesterday, a bit repetitive but I like it.

I’m struggling to find the episode with this building - I’ve no idea what it’s called.

Google reverse image search tells me it's The Buzludzha Monument on Stara Planina mountain in Bulgaria

That was featured quite a while ago. President ordered it then got the chop IIRC.

Used to watch it but got tired of the “what on earth can it be?” Format.

I don't know how many episodes there are in total but with 4 shown per day , I think they come around again quite quickly.
Some are fascinating , others a bit dull and not worth watching again .

The content is good but the dragging it out and 'over drama' of it busts my balls!
