Tyntesfield is a Victorian Gothic Revival estate near Wraxall, North Somerset, England, seven miles from Bristol. It was acquired by the National Trust in June 2002 after a fund raising campaign to prevent it being sold to private interests and ensure it be opened to the public.
The Gibbs family's fortunes originated in the establishment of a trading company by Antony Gibbs (1756–1816). Gibbs dealt mainly with Spain, and eventually took his two oldest sons (William and George) into partnership. After Antony's death, his sons built up a substantial trade in guano from the former Spanish colonies in South America. The firm's profits from this trade were such that William Gibbs became one of the richest men in England, and was able to finance the construction of Tyntesfield as a country home for his family.
