From 14th century churches to historic town centres, Hertfordshire has plenty of old buildings worth going to see, but some of them are at serious risk.

Historic England, the public body that looks after England's historic environment, oversees a register of listed buildings, sites and conservation areas it deems 'at-risk'.

Among them are 13 Hertfordshire buildings we could be at risk of losing forever.
