Background: A sprawling neo-romanesque palace known as Villa Piranesi is to be opened to the public as a museum. Restored furniture and works of art are being shipped into the compound.
Terrorists: Prevent the museum from opening by destroying one of its two main attractions; the antique sundial in the front courtyard or the grand celestial orrery in the back garden.
Counter-Terrorists: Protect the historical site against the terrorists.
- There is a Black Mesa SUV in the CT spawn. This vehicle is featured in Half-Life and its expansions. The SUV only appears in 1.6 and Condition Zero.
- In Counter-Strike 1.6 and earlier versions, there is a humorous reference. In the main hall and front room, there are "historical" posters with the text "The use of the lathe became very popular during this time period, but due to our r_speeds limits, the furniture is square".
- In Counter-Strike 1.6 and Source, there is a "Ticket Office" at the entrance to the right. By using the "noclip" cheat, players can access a secret room with a statue of a giraffe.
- On May 2, 2017, a reference to the map name de_piranesi was found in the maplist_csgo.txt file in Counter-Strike: Global Offensive.
