Sampson (horse)

Sampson, a Shire horse gelding foaled in 1846 in Toddington Mills, Bedfordshire, England, is the tallest and heaviest horse ever recorded.

Sampson, owned by Thomas Cleaver, stood 21.2½ hands high (i.e. 7 ft 2½ in or 219 cm at his withers) by the time he was a four-year-old, when he was renamed Mammoth.

His peak weight was estimated at 3,360 lb (1,524 kg).^[1] He was gelded at approximately one and a half years old, and his testicles were already the size of footballs.^[2]
