Sampson is the name of the biggest horse on record. This Shire horse was born in 1846 in the county of Bedfordshire, England.

The Shire horse has won many awards for being both the largest and tallest breed. They normally stand at 17 hands in height but in 1848 a shire horse named Mammoth stood at 21.2 hands.
