The church here is noted for its range of De La Beche monuments and a 600 year old yew .

There is an Iron Age camp at Lowbury, 2 miles away. The late Colonel Burne in his book, Battlefields of England, gives convincing reasons for placing the site of King Alfred’s victory at Ashdown over the Danes, in 871, on the Ridgeway nearby. This information was obtained at St Mary’s Church. There are 9 stone carvings, known as the Aldworth Giants. Queen Elizabeth I came to see the effigies with the Earl of Leicester. In 1976 the Yew tree, perhaps 1000 years old, was uprooted. It probably inspired the poem "For the Fallen" by Lord Tennyson of Freshford and Aldworth. It is quoted at remembrance day services:

They shall grow not old, as we that are left grow old: Age shall not weary them, nor the years condemn. At the going down of the sun and in the morning We will remember them.

Tennyson married Emily Sellwood of Pibworth Manor at Shiplake, and members of her family are buried here. There is a well 372 ft deep, believed to be one of the deepest in England.
