Blackheath is a relatively new (newer than Highgate) and affluent community. Many Georgian and Victorian homes, including the prestigious Paragon Crescent (now flats), were built on the (John) Cator Estate overlooking Blackheath Park.
Because of its proximity to the Royal Observatory in Greenwhich, a number of astronomers lived in Blackheath: Sir Edmond Halley, John Pond, and Nathaniel Bliss are all buried in St. Margaret's church yard. This photograph of Halley's gravestone was taken from IanVisits blog.
St Michael and All Angels Church was built in 1830 and the spire is nicknamed the "Needle of Kent."
