Each September some of Wales’ most iconic buildings and unusual sites welcome thousands of visitors as part of the annual Open Doors programme.
The annual event sees hundreds of attractions, events and activities open to visitors free of charge (for some of the events you need to book in advance) throughout the month.
Open Doors offers both local people and visitors the chance to explore new aspects of Wales’ culture and history.
Buildings and sites that are usually closed to the public will be among the many unseen gems opening.
The Open Doors Days is part of the European Heritage Days and offers a variety of unique opportunities.
