This year's Heritage Open Days, coordinated by the Civic Trust and funded by English Heritage, are 10-13 September. There is free admission to a range of properties across the country, including some that are not usually open to the public. Pictured above is Liverpool's Albert Dock, where warehouse tours are on offer. Other Liverpool properties that can be visited include the County Session House and St George's Hall (www. heritageopendays. org. uk).
