The town was first recorded in the Anglo-Saxon Chronicle in 795 as Wineshlauu, which translated into modern English means Wine's Mound. In the Domesday Book of 1086 it was recorded as Weneslai.
One of the finest buildings in Buckinghamshire is situated in this small town. Winslow Hall, which sits on the main road leading into the town from Aylesbury, was designed by Sir Christopher Wren in his early days before he was called on to redesign St Paul's Cathedral in London. The building, while smaller than other stately homes in the area to match its environment, is magnificently designed nonetheless.
Today the town has grown to house the expanding population, but the small town hasn't lost any of its quaint rural charm. The parish church is dedicated to St Laurence.
