Ligovsky Canal (Russian: Ли́говский кана́л) is one of the most extended channels of Saint Petersburg (Russia). It has been constructed in 1721, its length has made 23 kilometres. The channel was under construction for functioning of fountains of Summer garden. The channel delivered water from the Liga river (now called the Dudergofka) in ponds in Bassejnaya street (modern Nekrasov street).

History[edit]

The idea of construction of the channel belongs to the Russian emperor to reformer Peter I. He has decided to decorate Summer Garden with fountains, water should go to them by gravity. Small river Liga (now called the Dudergofka) near to a mouth (Dudergofskoye lake) became a water source. The author of the project became G. Skornyakov-Pisarev, he also supervised over building.

Except the basic function of actuating of fountains, the canal was used as a water main and as a defensive boundary, covering capital from the southeast part. Canal building has been finished in short the then terms - for 3 years (with 1718 on 1721). It is known that the channel crossed at least two bridges - under Moskovsky Prospekt and bridge on Znamenskya Square (in a photo). Later at building Obvodny Canal in the beginning 20th century has been constructed Yamskoi Vodoprovodniy Aqueduct, author of the project of the wooden bridge became Russian engineer Ivan Gerard. Later the bridge under Leninsky Prospekt has been constructed; Data on its dismantling are not present, it is probable it is filled up together with the channel and has remained underground.

Flooding of 21 September [O.S. 10 September] 1777 has destroyed fountains of the Summer garden and necessity for the channel has disappeared, besides as a result of it water in the channel became muddy and non drinkable. It has gradually become unfit for use and has been filled up in some stages:

  • In 1891-1892, the site from Tauride garden to Obvodny Canal has been filled up. Yamskoi Vodoprovodniy Aqueduct has been reconstructed in 1895, and has received name Novo-kamenniy bridge. Granite pools at the bridge have existed prior to the beginning 20th century when have been disassembled as superfluous.
  • In 1926, the site from Obvodny Canal to Moskovsky Prospekt has been filled up;
  • In 1965—1969, waters of the canal are lowered in Krasnenkaya River, and the channel has been truncated before crossing with Krasnoputilovskaya street.

Facts[edit]

Now near a railway line to luga channel waters go on an underground channel and leave on a surface near to Krasnenkaya River. There the canal is divided into two sleeves: on bigger canal waters are taken away in the Krasnenkaya River, smaller an underground site leaves in ponds of Aviatorov Garden. The length of the remaining part makes 11 kilometres.

On the bank of the channel in 1834-1838 have been constructed Moscow Triumphal Gate. It built mainly in cast iron.[1]

Filled up Ligovsky Canal became a hindrance of building of metro station Ploshchad Vosstaniya - at sinking an inclined tunnel of an exit on a surface wet stratum have strongly complicated works. They should be overcome, applying a caisson and to a breed frost a hydrochloric solution in 1950.[2]
