The access lane becomes the main street of the village and terminates on the bank of the River Thames, where it is surrounded by a cluster of three significant buildings. The Church of England parish church of St. Margaret was mainly built in the 14th and 15th century, and was restored in 1863 by the Gothic Revival architect William Butterfield. Mapledurham Watermill dates from the 16th and 17th century and is the last operational watermill on the Thames. Mapledurham House, the country house that is the headquarters of the Mapledurham estate, is one of the largest Elizabethan houses in Oxfordshire. On the village street inland from these three buildings can be found the Mapledurham Almshouses, a group of six almshouses built as a memorial to Sir Charles Lister who died in 1613, and now converted into two cottages.
