There's just over a fortnight until the launch of this year's Heritage Open Days.
As the website explains: "Heritage Open Days is England's biggest heritage festival involving 40,000 volunteers. It celebrates our fantastic history, architecture and culture; offering people the chance to see hidden places and try out new experiences - all of which are FREE to explore."
There is a wide range of things to see in Nottinghamshire from St Anns Allotments (apparently 'the oldest and largest detached town gardens in Britain, possibly the world'!) to the Majestic Theatre in Retford.
Full details are available on the Heritage Open Days website.
