Interlaken is a municipality in the Interlaken-Oberhasli administrative district in the Canton of Bern in Switzerland, a well-known tourist destination in the Bernese Oberland. Until 1891 Interlaken was known as Aarmhle. The convent of the Augustinian Canons was built around 1133 when it was mentioned as inter lacus Madon and lasted until 1528. The mill on the left bank of the Aare river was first mentioned in 1365 as Amuli, while the town on the right bank was mentioned in 1239 as villa Inderlappen. Previously, printing, textiles, and to a smaller extent watchmaking were also of importance, but today tourism is the most significant source of income. Interlaken is one of the oldest tourist resorts in Switzerland, and it remains one of the most popular. While some scattered neolithic flint objects, early Bronze Age swords and Roman era coins have been found near Interlaken, there is no evidence for a settlement in the area before the Middle Ages.
