The Piet Hein Tunnel [1] (http://tenplusone.inax.co.jp/archive/ned/ned_019.html) in Amsterdam, the Netherlands, is a 1.9 km long tunnel under an inlet of the IJsselmeer. It provides an East/West link between the city center and the A10 beltway encircling the city. It was completed in 1997. The tunnel, approaches and related buildings were designed by the hypermodernist Dutch architectural firm Van Berkel + Bos. It is named after the Dutch naval hero Piet Hein.
Piet Pieterszoon Hein (or Pieter Pietersen Heyn) (November 25, 1577 – June 18, 1629) was a Dutch naval officer and folk hero during the Eighty Years' War between the United Provinces and Spain.
Hein was born in Delfshaven (now part of Rotterdam), the son of a captain, and he became a sailor while he was still a teenager.
The PietHeinTunnel in Amsterdam is named in his honor, as is the former Dutch frigate Hr.
