Digitally delve into RIBA's collections to learn about current and lost buildings in the capital.


Young people will delve into the world-class architectural collections of the Royal Institute of British Architects and reveal online the history and significance of current and lost buildings in the City.

Read the daily articles by our young people, to be published on the RIBA's website during the week of London History Day, and discover what they found out about buildings associated with James Stirling's controversial Number 1 Poultry Place and Mies van der Rohe's unbuilt Mansion House Square scheme, the subjects of the exhibition Circling the Square.
