The Netherlands Carillon adjacent to Arlington National Cemetery was a gift from the people of the Netherlands to the people of the United States in 1954. The gift was made to thank the United States for its aid during and after World War II. First installed at a nearby site in 1954, the 49-bell carillon was moved to the present tower in 1960. A 50th bell was added following Dutch- and American-sponsored renovations in 1995, and dedicated on May 5, the 50th anniversary of the liberation of the Netherlands. On the 3rd of December 2019 the 50 dismantled bells arrived in Asten at the Eijsbouts foundry for a complete and general overhaul and three more bells are to be added to the carillon in honour of the 75th anniversary of the United States' participation in the liberation of the Netherlands. The first carillon at the Arlington National Cemetery was installed by Amvets in 1949 and dedicated by president Harry S. Truman. Presumably the Netherlands Carillon superseded the original carillon, though its fate is unknown. The total weight of the bells is 28 metric tons, the largest being 5,800 kg. The bells are constructed of a bronze alloy of approximately four-fifths copper and one-fifth tin. Each bell carries an emblem signifying a group within Dutch society. The smallest bells represent the youth of the Netherlands. The verses cast on the bells were composed by the Dutch poet, Ben van Eysselsteijn. The bell tower is an open steel structure reinforced by steel plates. It is 40 meters tall, with the glass-enclosed playing console and observatory about 25 meters from the ground. It stands on a quartzite plaza 93 feet square and is enclosed by a low lava stone wall. Two bronze lions, designed by Dutch sculptor Paul Koning, guard the plaza steps. A rectangular staircase leads to an observatory platform from which a small circular staircase winds up to the playing cabin. Thousands of tulips are planted on the surrounding grounds. Nearby is the United States Marine Corps War Memorial. The carillon is administered as part of the George Washington Memorial Parkway complex in Arlington Ridge Park. The carillon itself symbolizes the friendship between the people of the Netherlands and those of the United States—"a friendship so rooted in a common allegiance to the principles of freedom, justice, and democracy that it can weather any temporary differences of opinion." The Netherlands Carillon plays Westminster Chimeson the hour and plays American patriotic music twice daily. Special songs are played on May 5, July 4, September 2, and Thanksgiving Day. Concerts and recitals are performed on the carillon throughout the summer.
