Aerial photographs of Northern Ireland in online archive
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.
The archive captures familiar landmarks that have barely changed in the intervening years, such as the Giant's Causeway photo on the left, taken in 1952, and the aerial view of Dunluce Castle from 1948.
Here are three different views of the back of Belfast City Hall, taken in 1926 (left), 1929 and 1950.
This view of Belfast Port, looking towards the County Antrim coast, was taken in 1953.
This photograph of the ships in Belfast was taken 20 years earlier, in 1933.
While the River Foyle in Londonderry has stayed the same, these photographs taken in 1933 and 1949 show how much has changed in the intervening years.
