Marsfield is located 16 kilometres north-west of the Sydney central business district and is in the local government area of the City of Ryde.

The aboriginal name survives in a local park, the Wallumatta Nature Reserve, located at the corner of Twin and Cressy Roads, North Ryde.

[4] In 1874, following extensive debate including a Parliamentary Select Committee, the government resumed the Common for sale and settlement by small farmers, using the money to fund bridges across the Parramatta River at Gladesville and Iron Cove.

[5] Stately, historical Curzon Hall was built in the 1890s by Harry Smith and named after his wife Isabella Curzon-Smith.

The house was bought in 1921 by the Society of Saint Vincent de Paul which established St Joseph's Seminary on the premises.

The Marsfield-North Ryde Green Belt boundaries were revised and in December 1959, 688 ha (1,700 acres) of land was rezoned.
