Since its reopening, 380 years to the day from its original completion, Museum de Lakenhal in Leiden has been hailed as a landmark project, both for its radical and meticulous approach to weaving 21st century architecture into a centuries old fabric, as well as for its fully integrated vision of what a present day museum experience can be. Young Dutch architecture bureau Happel Cornelisse Verhoeven Architects teamed up with restauration specialists Julian Harrap Architects to deliver a fully reinvented, high-performing and future oriented museum that nevertheless honours history.
