Dangar Grid
The Dangar Grid is the layout of the streets in the centre of the central business district of Newcastle, Australia. Named after its designer, Henry Dangar, the Grid was designed in 1823 and implemented sometime thereafter. It covers the area from Brown Street to Pacific Street, and from Church Street to Hunter Street. History
Newcastle was in a state of decline when Governor Lachlan Macquarie commissioned Government Surveyor Henry Dangar to design a compact town plan for the city. This enabled Dangar to reinvent the colony's second-oldest settlement, providing it with a structural heart that still functions as Newcastle's central business district. When Governor Macquarie opened up the Hunter Valley for settlement he preserved Dangar's Grid by giving the newly formed Australian Agricultural Company  of land immediately west of Brown Street (now the Civic precinct and Newcastle West), preventing Newcastle from spreading westward until 1837. In the meantime, the city grew southward on a plateau. Dangar's Grid is unique in that it is situated on sloping ground between Christ Church Cathedral and the harbour. Rather than take advantage of the aforementioned plateau that is now The Hill, Dangar's Grid is "hill-draped between ocean and estuary", creating what Elizabeth Farrelly, the Sydney-based architecture critic, has described as "one of the country's – maybe the world's – most spectacularly sited towns".
