Alameda Central, Mexico City
Concierge.com's insider take:
This swath of green has been the place to promenade in Mexico City since the 16th century, when it was created. For evidence, check out the Museo Mural Diego Rivera at the eastern end of the Alameda, where you can see a 50-foot-long painting of people strolling through this very park. As is often the case in his large-scale works, Rivera includes a portrait of his wife, artist Frida Kahlo. It might be his frankest depiction of their relationship; the painting shows a maternal Frida holding the hand of a ten-year-old Diego (52-55-5512-0754; open Tues.–Sun. 10–6).
