10 Extreme Airport Runways You Won't Believe Exist

6. Cristiano Ronaldo International Airport - Madeira, Portugal

Renamed in 2016 after Madeira's most famous footballer, Cristiano Ronaldo, Madeira Airport has a runway like no other.

Back in 2000 the runway was extended over the water using 180 columns to hold it up. This makes it appear like it is built on stilts.

The unusual runway borders the ocean on one side and hills on this other. This means it is susceptible to high winds and turbulence, making it one of the most dangerous runaways to land a plane in Europe
