カレンベルク侯領
Sophia Charlotte was born in Iburg Castle in the Prince-Bishopric of Osnabrück, where her father held the title of a Protestant prince-bishop. In 1672 her family moved to the new episcopal residence in Osnabrück and finally in 1679 to Hanover, when Ernest Augustus succeeded his brother Duke John Frederick of Brunswick-Lüneburg in the Principality of Calenberg.
