The Caritas Well (Danish: Caritasbrønden) is the oldest fountain in Copenhagen, Denmark. It was built in 1608 by Christian IV and is located on Gammel Torv along the pedestrian street Strøget. It is considered one of the city's finest Renaissance monuments.
On the King's/Queen's birthday, copper balls covered in 24 carat gold, symbolizing golden apples, jump in the fountain. The tradition goes back to the 18th century.
