The Spanish Riding School is an Austrian institution dedicated to the preservation of classical dressage and the training of Lipizzaner horses, based in Vienna, Austria, whose performances in the Hofburg are also a tourist attraction. 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.
