Peninsula / Félsziget is a summer music festival taking place annually in Transylvania, Romania.

A peninsula ( from paene "almost" and insula "island") is a piece of land that is bordered by water on three sides but connected to mainland. The surrounding water is usually understood to belong to a single contiguous body, but is not always explicitly defined as such. A peninsula can also be a headland, cape, island promontory, bill, point, or spit. A point is generally considered a tapering piece of land projecting into a body of water that is less prominent than a cape. In English, the plural of peninsula is peninsulas or, less commonly, peninsulae. A river which courses through a very tight meander is also sometimes said to form a "peninsula" within the (almost closed) loop of water.
