Great Britain will have to overcome Argentina on clay after the hosts confirmed the venue for their Davis Cup World Group clash in February.
Britain will rely heavily on 20-year-old Andy Murray
The first-round tie will take place at the 15,000-capacity clay-surfaced Parque Roca in Buenos Aires.
Britain are unseeded and face a daunting trip to third seeds Argentina.
John Lloyd's team qualified for the elite World Group for the first time since 2003 with a 4-1 win over Croatia in September.
Britain have not won a World Group tie since Lloyd, Jeremy Bates and Colin Dowdeswell defeated Spain in 1986.
Following Tim Henman's retirement, Britain will rely heavily on Andy Murray, who is the only player in Lloyd's team ranked in the world's top 100.
Argentina boast 11 top-100 players, including number nine David Nalbandian, number 15 Guillermo Canas, number 20 Juan Ignacio Chela and number 23 Juan Monaco.
The tie will be played on the weekend of 8-10 February.
