Gulf of Finland between Helsinki and Tallinn60.0N 25.8E
The Gulf of Finland is the easternmost arm of the Baltic Sea that extends between Finland (to the north) and Estonia (to the south) all the way to Saint Petersburg in Russia. Here, in the part of the gulf between Finland and Estonia, water currents create swirled patterns which are interrupted by straight horizontal lines created by passing ships.
Other major cities around the gulf include Helsinki, in Finland, and Tallinn, in Estonia, both of which are visible here. Helsinki, the capital and largest city of Finland, is spread across a number of bays and peninsulas and over a number of islands. The inner city area occupies a southern peninsula, which is rarely referred to by its actual name Vironniemi.
Moving 80 km (50 mi) south of Helsinki, the capital and largest city of Estonia, Tallinn, spreads along the coastline of the Gulf of Finland for 46 kilometers. It occupies a surface area of 159.2 km2 (61.5 sq mi) in which 404,000 inhabitants live. It comprises 3 bigger peninsulas: Kopli peninsula, Paljassaare peninsula and Kakumäe peninsula.
