The Sea (Marine) Facade is a project of expansion of St. Petersburg, on Vasilievsky Island at the Neva river's mouth.

In these new territories, the Passenger Port of St. Petersburg was created, along with a considerable amount of residential and commercial space.

This project was implemented within the framework of a public-private partnership between the Saint Petersburg City Administration and the Marine Facade Management Company.

The primary goal of this project was to build the Passenger Port of St. Petersburg by reclaiming new territories of 476 hectares from the Neva Bay in the Gulf of Finland.

[citation needed] In 2008, the first phase of work was finished, and an area of 150 hectares was reclaimed for the port building.
