Our Mission
London's streets are an open-air museum, with over 3,532 plaques commemorating the notable men and women who have lived and worked in the capital. Yet many of these markers go unnoticed by the thousands who pass them daily.
Plaquer was created to change that. We believe history should be accessible, engaging, and fun to explore. Our mission is to help everyone discover the fascinating stories hidden in plain sight across London's neighbourhoods.
