Slovenia's highest mountain is Triglav at 2,864 meters. It's the tallest mountain in the Julian alps, but how does it compare to manmade buildings? Well, to build to the top of Triglav, you would have to stack the Burj al arab, the tallest building in the world, nine times on top of itself. And what about Ljubljana's famous nebotičnik? You would have to stack that classic skyscraper on top of itself to get to the top of Triglav. But Triglav is still relatively small compared to some of the other summits of Europe. It's 1.5 times smaller than Mount Blanc, for example. And when compared to Mount Everest, Triglav seems smaller still. You would have to put three Triglavs on top of each other to get to the top of Everest.
