Grange Park Opera’s glorious Theatre in the Woods, the first new opera house of the 21st century, opened to 14,000 visitors in 2017.

Guests arrive from two hours before the opera and, with a glass of champagne, explore this demi-Eden. In the convivial long interval, the audience settles into the two restaurants (the lucky eat inside the 15th century house), in picnic pavilions and marquees in the Crinkle-Crankle Garden, on the Croquet Lawn, and the Rose Parterre. Many just fling their rugs, unfold picnic furniture and do their own thing in the orchard under the mulberry, damson, apple and pear trees.
