The Davis Cup final between the Czech Republic and defending champion Spain will be at the O2 Arena in Prague next month.
The International Tennis Federation made the announcement on Tuesday.
The Czechs beat Serbia 4-1 on clay in the same arena in the quarterfinals, but are expected to use a faster surface to counter the Spaniards, who haven't lost on clay for 12 years.
The 100th final is from November 16-18.
The 02 Arena seats 13,000, and will also host the Fed Cup final between the Czech Republic and Serbia on Nov. 3-4. It's the first stadium to host both finals in the same year.
Spain will be chasing its fourth Davis Cup title in five years, including a 5-0 sweep of the Czechs at home in 2009.
The Czechs won their only Davis Cup title as Czechoslovakia in 1980.
