BTB Stud is pleased to introduce Castilly to the collection, a 13-year-old Holsteiner stallion of considerable substance and a pedigree that speaks for itself.


Standing 170 cm, Castilly is sired by Casall, one of the most influential jumping stallions of the modern era, out of a Contendro I mare. His damline traces back to one of Holstein's most successful broodmare families, with horses competing through to the 1.60m level across multiple generations dating back to the 1970s. It is the kind of pedigree that does not need explanation, only continuation.


In recent seasons, Castilly has competed at international 1.50m level under Thomas Brandt, and in September 2025 he was presented at Sires of the World in Lanaken, one of the most respected platforms for jumping stallions internationally.


He now settles into BTB Stud. His sport and breeding plans will be shared as the year unfolds.
