As we greet the beginning of the new quarter of the century, Domus has selected 13 authoritative “anniversaries” to remember works, events and architects who – ten, twenty, fifty, eighty and a hundred years from now – have given a fundamental contribution to contemporary architectural thinking, sometimes even deciding its course: from Le Corbusier's revolutionary reflections on urban dynamics of a century ago, to the works of fifty years and more that paved the way for new design and technological languages (Norman Foster's Willis Building; “Case Study House” programme, among others), to the interventions celebrating more recent birthdays (from MVRDV's Mirador, to Renzo Piano's Whitney Museum, Santiago Calatrava's Museu do Amanhã, to Jean Nouvel's Philharmonie de Paris), sure to still be here and celebrated again, possibly in another quarter of a century.
