Ministers will have to pay their way at what is now a luxurious conference centre near Siena, the Abbazia di Spineto built in the 11th century.
The closed-door consultations, hosted by Prime Minister Enrico Letta with 21 other ministers present, will start on Sunday and wrap up on Monday, the government said in a statement.
Letta said he wanted a "changing room" atmosphere at the retreat -- like a football team.
Ominously, the day the government was inaugurated on April 28 was marred by a shooting by a lone gunman outside the prime minister's office in which three people were injured.
Letta, a former youth political activist, has long been involved with the think tank world and is fond of US-style retreats, including by his own group VeDro which holds football tournaments during its summer gatherings.
