Plein 1813 is a monument commemorating the victory over Napoleon (denhaag.com, in English) and the end of the French era in the Netherlands. It’s a beautiful monument, surrounded by seasonal flowers that are replanted throughout the year in different colors. Traffic flows around both sides of the monument, providing a lovely view if you are taking tram 1 to Scheveningen.
