aerial photograph of tunnel vent along Sough Tunnel in Darwen Lancashire constructed in 1847 by the Bolton, Blackburn, Clitheroe & West Yorkshire Railway. The vents were constructed both to vent smoke from the steam engines of the day and also to relieve pressure as trains move along the tunnel. Because the pressure relief function is still important today the vents were renovated in 2020 and a grill cover added. The inaccessibility of the site meant the work was completed using a helicopter.
The easiest way to navigate this gallery is using the geographic menu on the left. The aerial photographs are all organised in galleries according to their location so start with the county and then choose the town or village. Wales & Scotland are at the bottom under the English Counties. If your looking at a picture and are not sure where it is, click the arrow on the upper right and it will show you which album it is in. Click the album name to see nearby images. There is a search facility ( bottom left ) but this only works with words I have put into it. That's fine for searches of places or well known buildings but in most cases I have not entered road name or a post code. The gallery is only a small part of my collection of UK aerial photographs so please Email if you would like to buy an aerial view of something not in the gallery. There are over 25,000 photos in the gallery and I have an archive of around half a million pictures going back to 1999.
