In common with the inhabitants of other Open field villages throughout the country, the people of Thatcham tilled the arable acres around the town growing their staple crops, wheat and barley and pasturing their herds and flocks on the common meadows. The names of these fields survive in one form or another, chiefly in street names and these include the North Field, the Worthy Field, Parsons Down (one third of which was held by the incumbent of St. Mary's Church), the Widmede (or wide meadow), Stone Field, Red Field and the Moor.
