Kohl's Fountain, Baroque fountain in Prague Castle, Czech Republic

Kohl's Fountain is a Baroque fountain in the second courtyard of Prague Castle, built in 1686 by sculptor Jeroným Kohl and stonemason Francesco Bartolomeo della Torre. Three stone steps carry a lower basin decorated with festoons, lion heads, mascaroons and cartouches bearing Emperor Leopold I's monogram "L"; Mercury, Vulcan, Neptune and Hercules support it, two Tritons carry the upper basin, and three lions hold a sphere.

The fountain dates from 1686 and was made by sculptor Jeroným Kohl, whose initials H.K. appear on the Vulcan figure, with stonemason Francesco Bartolomeo della Torre. It is also called the Lion Fountain or Leopold Fountain after Emperor Leopold I, in whose reign it was built. The Holy Roman Empire's double-headed eagle on the sphere was removed after 1918 and returned in summer 2020; the fountain was restored in 1982.

The fountain is called Kohlova kašna after its sculptor Jeroným Kohl, and also Lví kašna (Lion Fountain) for the lions on top or Leopoldova after Emperor Leopold I, in whose reign it was made. The lower basin carries cartouches with the imperial monogram "L".

The fountain sits in the second courtyard and is straightforward to reach by following the main pathways through the castle. Water flows from the Brusnice stream fed by a pond near Hvězda summer palace, so the fountain typically runs throughout the year and is easily visible.

The imperial monogram "L" on the cartouches of the lower basin stands for Leopold I, who ruled 1657–1705 while the fountain was being made. The sphere on top once carried a double-headed eagle of the Holy Roman Empire; it was removed after 1918 and put back in summer 2020.
