A gift from the Dutch people after American aid during and after World War II, the Netherlands Carillon has chimes that play daily on the hour between 10 a.m. and 6 p.m with automated concerts at noon and 6. Other patriotic tunes are played at special times through the year and summer concerts are presented most Saturdays and national holidays from May through September. The site offers a panoramic view of Washington, DC and is a popular picnic spot.
