Sky Gardens & Seismic Stations

Across the globe, visionary architects and brilliant engineers are often asked to defy the odds--and sometimes gravity itself--in order to build something spectacular. This episode, we visit Singapore's Pinnacle@Duxton, featuring the world's longest sky gardens. Then we hit the beaches of Brighton to see how the 450-foot, ultra-slender i360 viewing tower survives the coastal winds. Finally, we head to Naples where a stunning new rail hub, the Napoli Afragola station, was built in the shadow of Vesuvius and in an earthquake zone.
