The Meyboom or Meiboom plantation is the oldest tradition in Brussels, Belgium, attested since 1308. It is held every year on 9 August, the eve of St Lawrence's Day, and consists mainly in the planting of a beech at the intersection of the Rue des Sables/Zandstraat and the Rue du Marais/Broekstraat in the City of Brussels' Marais–Jacqmain district.
