Spain. But Madrid rather than Barcelona. Since over the last 50 years the Spanish won this clay slam 11 times, and the French only once, it should rightfully go to Spain.
that makes a lot of sense:
List of Spanish Winners and Runner Up's and their birth place!
1961 ESP Santana, Manuel - Madrid
1964 ESP Santana, Manuel - Madrid
1972 ESP Gimeno, Andrés - Barcelona
1974 ESP Orantes, Manuel - Granada
1993 ESP Bruguera, Sergi - Barcelona
1994 ESP Bruguera, Sergi - Barcelona
1994 ESP Berasategui, Alberto - Bilbao
1997 ESP Bruguera, Sergi - Barcelona
1998 ESP Moyà, Carlos - Mallorca
1998 ESP Corretja, Àlex - Barcelona
2001 ESP Corretja, Àlex - Barcelona
2002 ESP Costa, Albert - Lleida
2002 ESP Ferrero, Juan Carlos - Valencia
2003 ESP Ferrero, Juan Carlos - Valencia
2005 onwards - Rafael Nadal - Mallorca
so i see the reasoning for the place to be Madrid...
