Some of the most amazing views of London are from the top of the 1,016-foot skyscraper called The Shard.

And, wouldn’t you know it, couples who have been taking tours of the building are making pit stops in the 68th floor men’s room and having sex.

The secret sex romps were discovered by workers after they found a black thong in the bathroom after a recent party.

The new building actually opens to the public on February 1st – and officials are worried that it may become a hotbed for couples wanting to join the “Almost Mile High” club – especially with Valentine's Day right around the corner.
