Petergof (Russian: Петерго́ф), known as Petrodvorets (Петродворец) from 1944 to 1997, is a municipal town in Petrodvortsovy District of the federal city of St. Petersburg, located on the southern shore of the Gulf of Finland.

Petergof is named after the Peterhof Grand Palace, a sixteen-meter-high bluff lying less than a hundred meters from the shore.

The so-called Lower Gardens (Nizhny Sad), at 1.02 square kilometers (0.39 sq mi) comprising the better part of the palace complex land area, are confined between this bluff and the shore, stretching east and west for roughly 200 meters (660 ft).

At its foot begins the Sea Channel (Morskoy Kanal), one of the most extensive waterworks of the Baroque period, which bisects the Lower Gardens.

When the trend reversed, the need for housing made the University administration accommodate most students in Petergof, even those studying in downtown faculties, which has created certain tensions.

[6] Due to the extensive presence of research facilities, mainly belonging to St. Petersburg State University, Petergof was named a naukograd in 2005.

[10] Former sister cities: On 10 March 2022, the Polish town of Sopot terminated its partnership with Peterhof as a response to the 2022 Russian invasion of Ukraine.
