These are the works of Gaudi, who was into this sort of thing.
He wasn't so much into completing things though, as the Sagrada Familia is still under construction 86 years after his death.
Much of the burden of keeping things stable falls to this turtle, who has to support the whole thing.Even the sculptures are struggling - the knight's got his sword stuck, much to the delight of onlookers.
Where Gaudi was best, I think, was in ceilings.
If you look close, this one has glitter!
He was also good at sculpting nubbins and other protrusions.
These can be threatening, as you can see.
His staircases are not yet adapted to modern day obesity, so luckily Barry's been keeping trim.
But of course you can never go wrong with stained glass.
