Tresillian (Cornish: Tresulyan) is a small village in mid Cornwall, England, United Kingdom. It is three miles (5 km) east of Truro on the A390 road. Tresillian means "a place of eels" in the Cornish language, according to a 19th-century writer. However, modern toponymists agree that the name in fact translates as "farm/settlement of a man called Sulyen" (a Celtic personal name from British: sulo-genos, "sun-born").
A famous event of the English Civil War took place here in 1646. Thomas Fairfax sent a summons of surrender to Ralph Hopton who replied on March 8 that he was willing to negotiate terms. Fairfax agreed to negotiate and on March 10, 1646 both sides met at Tresillian Bridge. Hopton agreed to move his army to St Allen as a gesture of trust and goodwill allowing Fairfax to occupy Truro. The Wheel Inn at Tresillian is Grade II Listed building and is said to be to have been used as Fairfax's headquarters during the Civil War (Battle of Tresillian).
The village is mentioned as having a yearly fair in "Owen's book of Fairs" 1788 (https://archive.org/details/owensnewbookfai00owengoog)
A new church was built at Tresillian Bridge in 1904 (the font, bells, statue of St Anthony and pulpit from Merther were moved to the new church). The parish church of Merther was abandoned in the mid-20th century: previously it had been used occasionally, usually for funeral services.
There is a small Cornish cross on top of the church wall.
