Moulsford is a village and civil parish in South Oxfordshire. Before 1974, it was in the county of Berkshire, in Wallingford Rural District, but following the Berkshire boundary changes of that year it became a part of Oxfordshire. Moulsford is on the A329, by the River Thames, just north of Streatley and south of Wallingford. The west of the parish is taken up by the foothills of the Berkshire Downs, including the Moulsford Downs. Moulsford Bottom and Kingstanding Hill are traditionally associated with King Alfred and the Battle of Ashdown.

Moulsford Manor was the principal home of the prominent Carew family, who also lived at Carew Castle in Pembrokeshire. It was used by the American Army Air-Force during World War Two, then a nursing school, before being bought as a private residence for Kevin Maxwell in 1994, who lets it out for the filming of Midsomer Murders. Moulsford Railway Bridge, situated just north of the village on the Great Western Main Line, was designed by Isambard Kingdom Brunel.

Wallingford Castle is a medieval castle situated in Wallingford in the English county of Oxfordshire (historically Berkshire), adjacent to the River Thames. Established in the 11th century as a motte-and-bailey design within an Anglo-Saxon burgh, it grew to become what historian Nicholas Brooks has described as "one of the most powerful royal castles of the 12th and 13th centuries". Held for the Empress Matilda during the civil war years of the Anarchy, it survived multiple sieges and was never taken. Over the next two centuries it became a luxurious castle, used by royalty and their immediate family. After being abandoned as a royal residence by Henry VIII, the castle fell into decline. Refortified during the English Civil War, it was eventually slighted, i.e. deliberately destroyed, after being captured by Parliamentary forces after a long siege. The site was subsequently left relatively undeveloped, and the limited remains of the castle walls and the considerable earthworks are now open to the public.
