Alte Kirche (old church) on the island of Pellworm in the Nordfriesland district of Schleswig-Holstein, Northern Germany. Population: 1,200. In medieval times Pellworm was part of the larger island of Strand which was torn into pieces in a disastrous storm tide in 1634. Other remnants are Nordstrand and the Halligen. All these belonged to the historical region of Uthlande. Pellworm is accessible by ferry, departing from the neighboring Nordstrand, which is in turn connected with the mainland by a causeway.One of the largest hybrid renewable energy plants in Europe is to be found on Pellworm. It combines photovoltaic and wind energy to provide over 700 MWh/year of electricity.
