This square, located in the heart of Madrid, is more a must-experience attraction than a must-see one. Surrounded by cafes and bars, Plaza Mayor practically begs passersby to take a seat, order a coffee or glass of wine (depending on the time of day) and people-watch. Not only do throngs of tourists pass through, but multiple street performers plant their feet here to entertain. The square starts getting busy around 2 p.m. and will grow increasingly busy as night falls. If you find yourself in Madrid during the holidays, locals recommend visiting the holiday markets held in the plaza. 

Recent travelers acknowledge the touristy nature of Plaza Mayor – the souvenir shops, the less-than-gourmet yet overpriced restaurants, for instance – but for most travelers, Plaza Mayor still affords a lovely ambience. If you want to learn more about the history behind Plaza Mayor, which dates back to 1617, reviewers suggest you sign up for a walking tour. One of the city's most emblematic pieces of public art, the statue of Philip III on horseback, can also be found here.
