Old Windsor was the oldest Saxon town in Berkshire and the seat of Edward the Confessor. It continued in importance up until about 1100 when it was gradually overshadowed by the building of Windsor Castle two miles upstream. The parish includes within its boundaries most of Windsor Great Park, parts of which are open for public enjoyment and offer many pleasant walks. On the outskirts of Old Windsor is the Windsor Farm Shop, stocking a range of products from the Royal Farms and small local specialist suppliers.

The church of Saint Peter and Saint Andrew was first built in 1216, probably on the site of an earlier building. It was restored and rebuilt in 1863 but still retains its original Early English chancel and tower. The churchyard contains the grave of celebrated Georgian actress Mary 'Perdita' Robinson.

There are numerous opportunities for fishing and boating and, although there is much modern housing development adjacent to the main roads, the towpath walks still retain their rural charm. The southeast of the parish adjoins the county of Surrey where the road from Windsor to Staines leads to historic Runnymede. It was here on 15 June 1215 that King John sealed the Magna Carta.
