Stembridge Tower Mill is the only remaining thatched windmill in England and is under the care of the National Trust. Constructed in 1822 it was damaged by storms and left running via steam by 1897/8 and last used commercially in 1910. In 1969 Professor H. H.

High Ham Church is dedicated to St Andrew. There is documentary evidence for a church in High Ham in 1168 although the current buildings are later in date.
