A "Blue Plaque" is a commemorative sign installed on buildings to honor notable individuals or events associated with that location. These plaques are typically blue and feature white lettering, making them easily recognizable. They serve to educate the public about the historical significance of the site and the contributions of the person or event it commemorates. In the United Kingdom, the Blue Plaque scheme is managed by organizations like the English Heritage. The plaques can commemorate a wide range of figures, including writers, scientists, and politicians, such as Charles Dickens or Isaac Newton. This initiative helps preserve cultural heritage and promotes awareness of local history.
