What is "montaval"

Montaval (foaled 1953) was a French Thoroughbred racehorse and sire. Although trained in France throughout his career, his most notable achievements came in Britain: he was narrowly beaten in the 1956 Epsom Derby and won the King George VI and Queen Elizabeth Stakes in the following year. In total he won five times in a career of at least seventeen races which lasted from 1955 until November 1957. He was retired to stand as a stallion in Ireland and was exported to Japan in 1961.
