The Praca de Comercio is one of the largest squares in Europe and has tons of open space for your children to roam freely. There are a variety of upscale shops, bars, restaurants, museums and fantastic street performances going on all day long! Located in downtown Lisbon, the Praca de Comercio also displays beautiful works of art and sculpture, and is a great place for a leisurely stroll, a late lunch, or an evening out on the town. Kids will love watching boats pass by or locals fish for eels at the edge of the square!
