An online archive of photographs taken from planes between 1919 and 1953 provides a fresh view of Northern Ireland's past.

The Britain from Above website, run by English Heritage, collects tens of thousands of photos taken by Aerofilms Ltd, the first commercial aerial photography company in the UK.

More than 1,000 photographs of Northern Ireland have been published in the archive. Here is a selection of them.
