Cadw’s Open Doors month is a Wales wide programme that opens up more than 200 historic sites and “hidden gem” venues, from well known castles and abbeys to places that are usually closed or charge for entry. It sits alongside similar heritage open days across the UK, but with a strong Welsh focus and a mix of Cadw managed monuments and partner locations, so you can plan anything from a quick local visit to a full weekend of history hopping.
Who is this for?
Anyone who likes exploring on foot, taking photos, or learning the story behind a building will get value here, especially if you have been meaning to visit a landmark but have never quite justified the entry cost. It’s also useful for families and curious locals, as many venues add guided tours or one off events that give more context than a standard walk around.
