Berlin Tegel (IATA: TXL) is a funny airport. It’s there where according to Wikipedia, Aviation history dates back to the early 20th century, when the Prussian airship battalion was based there and the area became known as Luftschiffhafen Reinickendorf. After that a lot had happened in the area (for further details refer to your history books) until in the 1960s the current airport took shape. And what a shape it took! Tegel Airport is notable (or funny as I called it) for its hexagonal terminal building around an open square, which makes walking distances as short as 30 m (98 ft) from the aircraft to the terminal exit.
