Sultan the Pit Pony is the UK’s largest figurative earth sculpture!
A Pit Pony was a type horse bread especially for their strength and size and commonly used underground in coal mines from the mid-18th until the mid-20th century.
Ponies began to be used underground, often replacing child labour, as distances from pit head to coal face became greater.
At the peak in 1913 there were 70,000 ponies underground in Britain.
In later years, mechanical haulage was quickly introduced on the main underground roads replacing the pony hauls and ponies tended to be confined to the shorter runs from coal face to main road (known in North East England as "putting") which were more difficult to mechanise.
Typically, the Pony’s would work an eight-hour shift each day, during which they might haul 30 tons of coal in tubs on the underground narrow gauge railway.
Penallta Colliery (pictured above) was a coal mine, located close to Hengoed in the Rhymney Valley in the South Wales Valleys. Work began on Penallta Colliery in 1901 and by 1909 was in full production, in 1939 Penallta held the record for the most coal produced in a single week. Penallta Colliery closed in 1991 when political pressure forced its final closure.
