Manhattan boasts six large ventilation towers serving the four automobile tunnels that cross the Hudson and East Rivers: two each for the Lincoln and Holland tunnels, and one each for the Queens-Midtown and Brooklyn Battery Tunnels.

All sport an industrial art deco design reflecting their early/mid 20th century construction. Their large scale and lack of windows lends them an air of mystery; the exterior of the Battery Tunnel building was used as the secret HQ in the Men in Black films.
