We've seen plenty of images of old and modern London side by side, but few blend the two time periods as seamlessly as these shots.
Photos of London from around the start of the 20th century have been laid over modern day Google street view images of the same spot.
In some cases, the same buildings are still standing, lining up the two photos exactly.
The images have been put together by travel company Expedia, which has also put together an interactive map of the 13 London locations.
The map shows "just how many glimpses of untouched, historic beauty are still visible today".
