The Cwil Mound (; Polish: Kopa Cwila, Kopiec Cwila), also known as the Cwil Mountain (Polish: Góra Cwila), is a mound in Roman Kozà Âowski Park, in the city of Warsaw, Poland, within the Ursynów district. It was built in 1976, and has a height of 118 m.
The artificial mount was built in 1976, during the construction of the neighbourhood of Jary. It was made from the dirt excavated during local construction, and damaged building materials that were disposed off into the pile. It was proposed by engineer Henryk Cwil (1920âÂÂ1990), after whom it was later named. The Roman Kozà Âowski Park, centred around the mound, was opened in 1977.
