These remarkable images are some of the oldest known photos of famous cities around the world.
With the advent of photography in the 19th century, people were finally able to record their surrounding landscapes for the first time – and these then-and-now snaps offer a fascinating insight into how they used to be.

These early images of some of the most important cities across the world truly reveal how much the urban landscape has changed.
Most of them are almost unrecognisable when compared to their modern-day cityscapes.
A strangely deserted Trafalgar Square and Parliament Street can be spotted in the 1839 image of London.
Meanwhile Dublin’s earliest photo, taken in 1848, shows a group of smartly dressed Victorians posing in front of St George’s Church – which is now used as an office space.
New York’s Broadway, seen (left) as it is now, is unrecognisable compared to how it looked back in 1848 (right)
A modern day image of Macquarie Street, Sydney (left), shows just how much it’s changed since this photo (right), which was taken in 1855
A modern day view of San Francisco (left), with no abandoned ships in the harbour, compared to this photo (right) taken in 1851, one of the earliest such snaps
It is near impossible to distinguish downtown Los Angeles amongst the sprawling farm land in the 1860 photo, whilst the 1848 image of New York shows a quite different Broadway than the bustling one we know today.
It is rare to see people in the photographs not only because these cities were far less populated then but also because the exposure time for a photograph in the late 1800s was several seconds.
The few people that are present in the images would have needed to pose for quite a long period in order to make an impression on the final image.
