Roughly 170 years ago, Prague was entirely lit up by gas lamps. More than nine thousand gas lamps were in Prague in 1940. Today gas lamps are along the Royal Route, from the Powder Tower to Prague Castle, Celetná Street, Vejevodov, the northern part of the Old Town, and more.

In 2002, Prague began reimplementing gas lamps throughout the city beginning on Michalská Street. In 2010, 46 gas lamps were placed on Charles Bridge, which is the only gas lit bridge in the world. Larger European cities have boasted gas lamps since the beginning of the 19th century. The gas industry faced occasional gas explosions, mostly due to lack of experience.

Today other cities such as London, Dublin, Berlin, and Strasbourg also light some of their streets with gas lamps. Gas lamps are safe, in fact, the safety regulations for gas lamps are stricter than electric ones. Lamps are equipped with thermoelectric fuses and are regularly checked in the field.

You can recognize a gas lamp by the glass cover, electric lamps are made with frosted glass and clear glass gas lamps. The lamps are turned on and off by a remote-control signal from the central dispatch at the same time as the electric. Today there almost 700 gas lamps in Prague.
