Hipodromo do Campo Grande
Either of the two annual dressage events that take place at the Hipodromo do Campo Grande are worthwhile things to do in Lisbon. The Internacional Concurso Oficial de Saltos (which includes a Nations Cup) takes place in May and lasts four days.
Also held at the Hipodromo do Campo Grande, the Festival Internacional do Cavalho Puro Sangue Lusitano takes place in June. The Lusitano, native to south-western Iberia, is the oldest saddle-horse in the world.
