Nunnington Hall is a Grade I listed mansion owned by the National Trust and open to the public. The parish church, dedicated to All Saints and St James, is also a Grade I listed building. The nave and chancel date from the late 13th century and the tower from 1672, but the tower, porch and vestry were rebuilt in 1883-4. There is a fine 17th century pulpit. The village has 28 other houses and other objects listed Grade 2, including the early 18th-century bridge over the river.
Nunnington railway station lay one mile west of the village. It closed to passengers in 1953.
Former residents of Nunnington have included the writers Annie Keary (1825–1879) and Eliza Harriett Keary (1827–1918) in the 1840s, while their father William Keary (died 1859) was rector. Annie Keary's children's book Mia and Charlie; or a Week's Holiday at Ryedale Rectory (London/Winchester, 1855) recounts the story of the Proud Lady of Nunningham, who haunts the hall.
