Maison du Sport International

The Maison du Sport International (International House of Sport) is an office complex opened in 2006 in Lausanne, Switzerland, via a joint venture between the City of Lausanne, the Canton of Vaud and the International Olympic Committee (IOC). It was created to entice all the World's sports governing bodies (also known as International Federations or IF's) to bring their headquarters to Lausanne, in order to improve their proximity to the headquarters of the IOC, and thus improve communications between these bodies.

However, many international federations have their offices elsewhere, often in a country where the specific sport traditionally has a regular following. With modern communications, the need for physical presence is also not as important anymore.

Currently the tenants of the MSI, include these International Federations:
FAI Fédération Aéronautique Internationale
FITA International Archery Federation
IBAF International Baseball Federation
BWF Badminton World Federation (branch office)
FIBT International Bobsleigh and Tobogganing Federation
AIBA International Boxing Association
UEC Union Européenne de Cyclisme
WBF World Bridge Federation
ICF International Canoe Federation
FICS International Federation of Sports Chiropractic
FIMS International Federation of Sports Medicine
FIE Fédération Internationale d'Escrime
FIAS Federation International Amateur de Sambo
WBSC World Baseball Softball Confederation
FISA International Rowing Federation
WTF World Taekwondo Federation (branch office )
