The Royal Library Garden, also known as the Library Garden, is located between Christiansborg Palace and the Royal Library on Slotsholmen.

The garden was established in 1920 on the site of Christian IV’s old naval harbour, Tøjhushavnen, and was designed by Jens Peder Andersen and Thorvald Jørgensen. In the center is a basin and a water sculpture donated by the Ny Carlsberg Foundation on the occasion of the Black Diamond. The garden also features a sculpture of Søren Kierkegaard and column bases from the old Christiansborg, used as flower stands. It is open to the public and visited by both locals and tourists for peaceful walks and relaxation. With its central location and historical significance, the garden is an important recreational area in Copenhagen.
