Greenwich, NSW
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Greenwich is a leafy harbourside suburb on the Lower North Shore of Sydney, set on a peninsula where the Lane Cove River meets the harbour, about seven kilometres north-west of the city centre in the Municipality of Lane Cove. It was home to the Cammeraygal people of the Eora nation, who lived along these foreshores. The suburb takes its name from Greenwich on the Thames in London, echoed by nearby Putney, Woolwich and Henley; the name first appears when George Green subdivided his land here in 1840. His Georgian sandstone residence, Greenwich House, built in 1836, still stands. The eastern tip, Manns Point, recalls Gother Kerr Mann, an early owner. Today the suburb offers harbour views, pockets of bushland and a netted harbour swimming pool.
