It is now the seat of the parliament () of Lower Saxony.

The first building on the site was a Franciscan friary, constructed in about 1300, which was abandoned in 1533 after the Protestant Reformation. In 1636, George, Duke of Brunswick-Lüneburg, began converting the monastery into a rather small late-renaissance palace as his residence as ruler of the Principality of Calenberg. The former monastery church served as a castle church and royal burial place. His son, Elector Ernest Augustus, had it enlarged and modernized and added a theatre in the late 17th century. The principality was elevated to the Electorate of Hanover in 1692. In 1742 the north-west wing was renewed. On May 28, 1660 Ernest Augustus' son, George I of Great Britain was born at the Leine Palace.
