This fountain in the inner courtyard of the Frederiksborg Castle was created in 1620 to demonstrate King Christian IV’s command of the waters of Denmark and Norway. The bronze figure on top is Neptune, the Roman god of the sea. In the pedestal niches are deities of rivers, springs and water. They are surrounded by naiads who are water nymphs from Greek mythology. Along the marble basin are mermen shown blowing twisted conch shells. They are tritons, the messengers of the sea.
