Since 1987, a number of artists have left their mark on the lovely Park of Music, which is located in Kildeparken, by planting a tree to commemorate their visit in Aalborg. There are currently 94 trees.
Sir Cliff Richard was the first artist to plant a tree in Kildeparken in 1987 when he performed in Aalborg Congress & Culture Centre. Since then, many more trees and artists have joined and today, more than 80 great artists have left their mark on the park with oaks and wild cherry trees.
