Ekaterinhof or Catherinehof is a historic island park that began as an 18 century empress's estate in the south-west of St Petersburg, Russia. Its name originated in 1711, when Peter the Great presented the Island and adjacent lands along the eponymous Ekateringofka River
to his wife Catherine, whose name they memorialize.
The emperor apparently conceived Catherinehof as the first imperial estate located on the road leading from the capital to his main summer residence, Peterhof.
