Prague Pneumatic Post

The Prague pneumatic post (Czech: Pražská potrubní pošta) is the world's last preserved municipal pneumatic post system. It is an underground system of metal tubes under the wider centre of Prague, totalling about 55 kilometres (34 mi) in length. Known as the Old Lady of Czech telecommunications, the system started service in 1889 and remained in use by the government, banks and the media until it was rendered inoperative by the August 2002 European floods. The current owner, Telefónica O2 Czech Republic gradually is repairing and conserving the system; due to limited funding the system remained inoperative as of March 2007.

Famous quotes containing the words pneumatic and/or post:

    “Food probably has a very great influence on the condition of men. Wine exercises a more visible influence, food does it more slowly but perhaps just as surely. Who knows if a well-prepared soup was not responsible for the pneumatic pump or a poor one for a war?”
    —G.C. (Georg Christoph)

    “To the old saying that man built the house but woman made of it a “home” might be added the modern supplement that woman accepted cooking as a chore but man has made of it a recreation.”
    —Emily Post (1873–1960)
