A copy of a JMW Turner painting that has never before been on public view has been put on display. “The watercolour, showing the Gothic Cross over the lake at Stourhead, Wilts, has been in the Tate archives since it was bequeathed in 1856. A copy of the work, which was painted in 1798 when the artist was 23, is being exhibited at the National Trust-owned Stourhead house and garden this month.”
