Dacha life on the Gulf of Finland flourished at the end of the XIX century. In 1898, the supreme decree approved the position of the Committee of Ministers and decided: "To arrange a resort in Sestroretsk between the sea and the river Sestroretsk." These lands on the shore of the Gulf of Finland were perfectly suited for the construction of a resort: a pine forest on the shore, a clean bottom of the bay, fine sand.

Kommersant tells about the dacha Sestroretsk (you can read the article at the link).
