Kengo Kuma Designs Protective Gallery for Angers Cathedral's Medieval Polychrome Portal

architecture-design · 2026-04-30

A new gallery, crafted by Japanese architect Kengo Kuma, has been inaugurated at Angers Cathedral in Maine-et-Loire, France, with a budget of €4.3 million, entirely financed by the French government. This structure safeguards the 12th-century polychrome portal, which still exhibits 70% of its original hues, uncovered following a cleaning in 2009. Replacing a medieval edifice that was demolished in 1807, Kuma's design emerged victorious in a competition held by the Direction Régionale des Affaires Culturelles (Drac) des Pays de la Loire in 2019. The 11-meter-high concrete construction, supported by eight micropiles to protect archaeological sites, includes five openings for viewing the portal, while two luminaires cast gentle light to preserve the sculptures. Valérie Gaudard remarked that the project had been in the works for decades.
