The lively nightspot and market square Nieuwmarkt, found in the old city centre just east of the Red Light District, has been a centre for commerce and socialising in Amsterdam since the 17th century. Created by filling in the surrounding canals, the square's location just inside the old city gate made it a popular spot for traders and shoppers looking for fresh produce. Today, Nieuwmarkt still holds a daily market as well as an organic fare market on Saturdays, but arguably its biggest draw is the amount of cafés, restaurants and coffeeshops that surround it, making this square a perfect place to spend a sunny day sitting on a terrace. The Nieuwmarkt metro stop can be found on the square, which caused quite a bit of protest during its construction but now serves as one of the city's most central and most used stops on the metro service.
