Balloonist Andy Collett was floating over South Gloucestershire in July 2012 when he spotted something striking: a heart-shaped meadow in the center of a stand of oaks. “This was the most amazing sight I have ever seen from the sky,” he told the Telegraph. “It was a perfect heart hidden away from view — you would not know it was there.”

It turned out that 70-year-old Winston Howes had planted the wood to commemorate his 33-year marriage to his wife, Janet, who had died 17 years earlier of heart disease. In the months after her death he filled a six-acre field with thousands of oak saplings but left a heart-shaped clearing in the center, its point aimed at her childhood home.

“I came up with the idea of creating a heart in the clearing of the field after Janet died,” Howes said. “Once it was completed we put a seat in the field, overlooking the hill near where she used to live. I sometimes go down there, just to sit and think about things. It is a lovely and lasting tribute to her which will be here for years.”

The clearing was not visible from the road and remained a family secret until Collett spotted it. “You can just imagine the love story,” he said.
