aerial photograph Polruan Castle Cornwall England UK. Polruan Blockhouse was built by Henry VIII to defend the entrance to Fowey River alongside similar defenses on the other side of the river. A chain was laid across the river to another Chain Tower at Fowey so that the chain could be raised in times of danger to prevent ships sailing up the river.It was intended to prevent a repeat of the raid on the town in 1457. Polruan Blockhouse is one of only five Chain towers known in England with it and its opposite companion tower being the oldest. The tower became obsolete in the 16th Century when St Catherine's Castle was constructed, although it was reactivated during the English Civil War.
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.
