Which city is known as the horse capital of the world, located in Kentucky?

Lexington is recognized as the "Horse Capital of the World" due to its historical and cultural significance in the thoroughbred horse industry. The city is surrounded by fertile bluegrass pastures, ideally suited for raising thoroughbred horses, and is home to numerous Kentucky horse farms. Lexington also hosts many significant horse racing events, such as the Kentucky Bluegrass Stakes, and holds a prominent place in the breeding and training of racehorses. The region's long-established tradition in equestrian sports, complemented by institutions like the Kentucky Horse Park, further solidifies Lexington's reputation in this area. This deep-rooted connection to the horse industry and the ongoing activities surrounding it make Lexington synonymous with horse culture while the other cities mentioned lack this specific association with equestrian excellence.
