Great Britain will play their Davis Cup quarter-final against Serbia on outdoor clay in Belgrade.
The tie, from July 15-17, will take place at the 6,100-seat Tasmajdan Stadium in the city centre.
Andy Murray has already committed to playing, fitness permitting, as Britain continue the defence of their title.
Whether world number one Novak Djokovic also features remains to be seen, and the choice of clay potentially makes it less likely Serbia's star player will turn out.
The tie comes at a hectic time of the season, sandwiched between Wimbledon and the Olympics, which will be a hard-court tournament.
Serbia have two other top-70 players in Viktor Troicki and Dusan Lajovic but Britain would fancy their chances without Djokovic.
GB captain Leon Smith said: "Now we know the surface and venue our preparations for the Serbia tie can go to the next level.
"It is going to be an exciting contest in Belgrade and we can't wait to get back together as a team and continue our defence of the title."
Britain have met Serbia once before in Davis Cup in Glasgow in 2006. Murray and Djokovic both played as teenagers, with Djokovic winning both his singles rubbers in a 3-2 victory.
