Each week we join both the Centerville farmers market and the Winterthur farmers market. We begin in early July and go till the first or second week of October. Centerville The Centerville market is on Thursdays, from 1:30-5:30, at the Lower Brandywine Presbyterian Church Parking lot. It's on the corner of Old Kennett Rd. and Rt. 52 (this is temporary this year due to the construction in Centerville). Winterthur The Winterthur farmers market takes place Saturday mornings 9:00 till noon. It is on Rt. 52 (and Old Kennett Rd.) just south of the museum entrance.
