Since 18/04/1997, a partnership between cities unites Barth with the Swedish City of Simrishamn, which is located in the southernmost and most fertile countryside of Sweden, about an hour by car from Trelleborg. About 20,000 inhabitants live in the idyllic, maritime small town, 7,000 of whom live in the City of Simrishamn. A lively port and a picturesque part of town invite you to a visit.
The City of Bremervörde, with which the City of Barth fosters a partnership relationship, is situated in the picturesque countryside between Hamburg and Bremen, by the Vörder See (a lake), which is an attractive nature and leisure time paradise. Over the centuries, Burg Vörde (a castle) was often heavily fought for and also during the thirty-year war between the Danish, imperial and Swedish armies. In spite of some destruction, the castle could be preserved and today provides room for a museum of local history and for the district archives. The restored Dutch windmill is a landmark of the town. Bremervörde provides a viable business life and attractive shopping facilities.
The City of Varel, with which Barth concluded a treaty of friendship on 21/12/1990, is located on the North Sea on Jade Bay and is harmoniously surrounded by forests. Varel considers itself a garden city and the economical and cultural centre of the northern Oldenburg region. With its mild maritime climate and its medicinal sea silt, the quiet Dangast Seaside Resort provides relaxing stays to families and visitors to the health resort.
In June 2000, Barth entered into an additional partnership relationship with the City of Kolobrzeg (the former Kolberg), which is the largest Polish health resort. Its location close to the Baltic Sea provides its visitors with a wonderful view of the port mole and of the shipping traffic in the port canal. Particularly worth seeing are the numerous churches, the natural monuments and the cathedral. The historic old part of town presents a flourishing townscape of Kolobrzeg.
