What is a blue plaque?

Blue Plaques are internationally recognised symbols commemorating places, spaces, events and personalities of cultural or historical importance. The placement of the iconic round plaques with white text on a blue background began in 1866, more than 150 years ago.
The Magaliesberg Association for Culture and Heritage are placing Blue Plaques at heritage sites throughout the Magaliesberg Biosphere.
