Its area covers 747 km<sup>2</sup> (including 274.9 km<sup>2</sup> of sea). It was the first area to be designated a national park of the former Soviet Union. It is the largest park in Estonia and one of Europe's biggest national parks. Its charter calls for the preservation, research and promotion of North-Estonian landscapes, ecosystems, biodiversity and national heritage.
History
The name Lahemaa originates from the most thoroughly studied and visited part of the North Estonian coast, where four large peninsulas (Juminda, Pärispea, Käsmu and Vergi) are separated from each other by four bays (Kolga, Hara, Eru and Käsmu). Lahemaa translates roughly as "Land of Bays".
There are four manors situated in the national park: Palmse manor, the picturesque Vihula manor, Kolga manor, and the baroque Sagadi Manor, Estonia's most visited manor which together with the other three comprise one of the most unusual group of manors in the country.
Prior to 1991, the Soviet Union operated a large secret submarine base at Hara. The base was built in the 1950s during the height of the Cold War.
