Museo Helga de Alvear
After a day spent meandering through medieval passageways and marveling at ancient churches, this contemporary art museum, presided over by one of Europe's great modern art collectors, is a breath of fresh air. Highlights include sculptures by Ai Weiwei and Dan Graham and paintings by Josef Albers and John Baldessari. A much-anticipated renovation by Tuñón Arquitectos (of Atrio fame), finished in 2021, added soaring galleries and multimedia spaces to house the gallerist's entire collection. If visiting on a weekend, be sure to reserve entry in advance online.
