Throughout September, Cadw is hosting the Open Doors festival. 

Over 200 historic landmarks across Wales will offer visitors an exciting lineup of free events, guided tours, and immersive experiences = some of which have never been accessible to the public before. 

The Open Doors initiative is part of the wider European Heritage Day festival – it will provide a unique opportunity for people of all ages to connect with the past, experience rich heritage, and uncover captivating stories that have shaped Wales’ history. 

To celebrate, we’re offering the chance of winning a one-year Cadw membership*. 

The process is simple:
