boundaries specialize in horses, and another five in the adjacent communes. Chantilly has one farrier and there are another four nearby. Similarly, there is one saddler and another seven based outside town. Chantilly has two racehorse dealers; another five are based in the surrounding area. A horse-racing school, AFASEC's "The Windmill" is based in Gouvieux and provides instruction to 185 jockeys and trainees, many of whom are housed in a facility in Chantilly proper. Finally, there are plans to build a biomass plant that will use the manure generated by the stables. Racecourse The racecourse hosts 25 meets and 197 races every year, including the prestigious Prix du Jockey Club and Prix de Diane. It is one of six Parisian racecourses managed by France Galop, although it is owned by the Institut de France. When it was threatened with closing, 24 million euros were raised to modernize it by a public interest group that included the mayor's office, France Galop, the Institute of France, the CCAC, an intergovernmental commission of Chantilly-area governments, the Oise council, the Picary regional council, and Prince Karim Aga Khan. Work was completed in 2007 and included a new ring, repairs and modernization of the stands, a scale and a new parking area. It now receives 40,000 visitors a year. Tourism Tourism in Chantilly centers on the Domaine de Chantilly, which owns the chateau and associated lands. The chateau itself had roughly a quarter million visitors in 2007, while the Living Museum of the Horse drew 149,000. The other big tourist draw is Chantilly Forest, which received as many as four million visits yearly. This makes it the 7th most-visited forest in the Paris region. Most of the visitors are day excursionists. Unlike Versailles and Fontainebleau, foreign tourists account for only 15% of the traffic, which can at peak times reach 20,000 simultaneous visitors to the various Domaine properties. Every year an international show jumping competition, the Chantilly Jumping, which is part of the Global Champions Tour, is held in 2 arenas in the middle of the racecourse. At the heart of the Parc naturel régional Oise-Pays de France, Chantilly is surrounded by history. The medieval city of Senlis and its cathedral are only ten kilometers away and the abbeys of Chaalis, Moncel, and Royaumont are only slightly further, as is the priory at Saint-Leu-d'Esserent. Natural attractions also abound, such as the forests of Halatte and
