Derek Gale lives at 7, Eagle Lane in Watchfield, I visited him to deliver brochures, and would encourage visitors to Open Studios to go to Watchfield on the way to Longcot.
Watchfield can be reached by turning right off the A420, driving through Shrivenham and turning left into Watchfield High Street, Eagle Lane is about half a mile down the High Street on the left, with the wonderful looking Eagle Pub signed from the High Street.
Alternatively and more safely, drive on further to the next roundabout and take the third turning to Watchfield, High Street is now on your right.Parking on the High Street is essential, not on Eagle Lane because it's very small. Derek's website
The number 66 bus will drop you at the road end.
Here's a photo of Derek's studios at the entrance to the garden:
In addition to visiting Derek's garden studio and enjoying his fine art photography, there's his garden to enjoy, and possibly cakes:
And the Eagle pub:
And the King and Queen pub at Longcot is under new management and apparently very good.
