These are two parts of one map created in 1914. I've picked them out to show where the school used to be in Lew, next to University Farm and the Post Office a little to the east just before you get to Trinity Church.
This map was produce for the sale of the Lew Estate in 1914. There used to be a Post Office and a school in Lew, both shown on this map between University Farm and Holy Trinity Church on the main road.
In October 2012 the Bampton Environmental Watch Group had a wonderful talk given by John Leighfield on the history of maps and in particular maps of Oxfordshire and Bampton. It was very interesting to note that the first maps of Bampton showed the rivers and streams but no roads, showing the importance of waterways. It really is worth looking at the maps of Bampton carefully, you'll see just how old some buildings are, where the mill was in Bampton and Kerwoods Yard which was one area for the very poor with dwellings that had no land with them, they afforded the occupier a roof as opposed to 'the park bench' but no land on which to produce any food. It's referred to in early census forms and people come to Bampton asking where it is - it's on page 15 of this pdf
