"Museu Calouste Gulbenkian’s heroic collection of Eastern and Western art is nearly incomparable in Europe. Hidden away in a complex inside leafy Gulbenkian Park, the museum is a chronological treasure trove of epic art that spans ancient Egypt , Mesopotamia, the Qing dynasty, and the Roman Empire, among others. In August, the institution throws Lisbon ’s premier jazz concert series, Jazz em Agosto—meaning that once you’ve had your fill of Egyptian mummy masks, fascinating Roman gold medallions, and René Lalique’s unearthly dragonfly brooch, you can chill on the expansive lawn for a little live music."
