Salvador Guardiola Fantoni founded his stud farm in 1943 with mares and stallions from Roberto Osborne Stud Farm in Estepa. Today, his heirs continue the family tradition on their farms, one of which is located only 5 kilometers from Utrera, El Pinganillo, while the other, Los Isletones, is in the Guadalquivir marshlands. The first awards were earned at the Select Livestock Exhibit of 1944 and 1945, and recent awards are earned in Seville, Jerez, Malaga and Madrid.
" this farm has many offspring of the incredible bay stallion Centella V - who was a champion of Spain, and was represented at the championship at 18 years old, and very much admired. He is an extraordinary horse, great power and strength. The Guardiola horses are inclined to be very substantial, great bone, and slightly convex heads - they are often fairly line bred, which makes the breed truer in many cases. Many are bay and black, although they do not specialize."
