The Garden of The Royal Library is a charming hidden gem tucked away behind The Black Diamond in Copenhagen. Designed in the 1920s, this public park offers a peaceful escape with blooming flowers, shady trees, and a quaint pond. You can admire statues like the bronze figure of philosopher Søren Kierkegaard and a water sculpture that shoots water every hour. It's a lovely spot to wander and relax, especially during spring and summer when the garden is in full bloom.
