In 1648 the Prince-Archbishopric was transformed into the Duchy of Bremen, which was first ruled in personal union by the Swedish and from 1715 on by the Hanoverian Crown.

In 1813 the Duchy was restored to the Electorate of Hanover, which - after its upgrade to the Kingdom of Hanover in 1814 - incorporated the duchy in a real union and the ducal territory, including Hollern and Twielenfleth, became part of the Stade Region, established in 1823.

The community is located in Altes Land (English: Old Land), the largest fruit orchard in Europe, directly by the Lower Elbe river (German: Unterelbe) between Stade and Hamburg.

The northwesterly two thirds of the Elbe island Lühesand forms part of the municipal area.

The main bus line is 2357, which covers the following areas: Stade - Hollern-Twielenfleth - Steinkirchen - Jork - Hamburg-Cranz.
