The leading horses and riders of the school also periodically tour and perform worldwide. It is one of the “Big Four”, the most prestigious classical riding academies in the world, alongside the Cadre Noir, the Portuguese School of Equestrian Art, and the Royal Andalusian School.
The riding school was first named during the Habsburg Monarchy in 1572, long before the French manege of Antoine de Pluvinel, and is the oldest of its kind in the world.
The Spanish Riding School is located between Michaelerplatz and Josefsplatz inside the Hofburg in central Vienna. Performances take place in the Winter Riding School, built between 1729 and 1735. The Winter Riding School is a sunlight-flooded hall, mainly white with some beige and light grey, with a portrait of Emperor Charles VI above the royal box and opposite the entrance (to which the riders always salute before they ride), which measures 55 by 18 meters and is 17 meters in height.
The Spanish Riding School also has summer stables in Heldenberg-Wetzdorf-Lower Austria. The 68 resident stallions are taken there in July and August for seven weeks, where they are kept in stalls with paddocks. The horses are not schooled during this period but instead are hacked in the nearby forest.
The methods used by the Riding School are based on François Robichon de la Gueriniere. It is a common myth that the movements were developed to aid in battle; in fact, they were used to strengthen the war horse’s body and mind and make him a supreme athlete, not to actually attack. All movements are based on those naturally performed by the horse when at liberty, with the exception of one-tempi changes.
Performances at the Spanish Riding School were originally only presented to guests of the Court, and then when they were finally opened to the general population at the turn of the century, it was only for special occasions. However, after the fall of the Austro-Hungarian empire in 1918, the school opened up regular performances to the general public to help pay for its upkeep.
