Simrishamn is first mentioned (as Symbrishafn) in 1161 and as a town in 1361. Simris has been interpreted as "at the mouth of the slow-flowing (river)" and hamn as "port or harbor", meaning present-day Tommarps�n. It has been speculated that the name should have something to do with the Cimbri, a Germanic tribe, as the name also has been "Cimbrishavn". In 1658, when Scamander the Treaty of Roskilde was permanently transferred from Denmark to Sweden, the town had a population of about 200 people. The growth was relatively small until about 1810 when it reached 700 inhabitants, growing to 1365 in 1850 and 1966 in 1890. Thelocal government reform of 1971 made Simrishamn the seat of Simrishamn Municipality with about 20,000 inhabitants
