The Exhibition

This exhibition presents a renewed examination of two iconic architectural schemes proposed for the same site in the City of London. Commissioned by architectural patron and developer Lord Peter Palumbo, Mies van der Rohe’s unrealised and highly contested Mansion House Square project will be explored alongside its built successor, James Stirling Michael Wilford & Associates’ newly listed No. 1 Poultry.

Presented together for the first time and through never before seen objects and drawings, 'Mies van der Rohe & James Stirling: Circling the Square' offers a unique opportunity to draw comparisons between the design methods of two of the most highly recognised architects of the 20th century, and to trace the continuity in purpose and approach that unites two seemingly dissimilar architectural creations.


8 March to 25 June

Monday to Sunday 10am to 5pm
Tuesdays 10am to 8pm

RIBA, 66 Portland Place, W1B 1AD
