@tinley23 It was part of the Christmas Light Show at Belton House, Leicestershire ( https://www.nationaltrust.org.uk/belton-house). I am pretty sure it has finished now and you had to have tickets but well worth the visit. If you get a chance next year, and if they repeat it which I think they will, it is a lovely walk with all kinds of attractions and about a mile walk. The youngsters especially enjoyed roasting marshmallows on a massive fire pit!
