The world seems to be changing quicker than ever.
You only have to look round the to see how much it has changed.
Central Square has emerged on land outside the city railway station, Guildford Crescent has gone and the skyline now has tall blocks of student accommodation.
But, looking through our picture archives, they are nothing compared to the changes in the city since 1900.
These brilliant mirror images show exactly what the city looked like and what those exact same spots look like today.
1900
The building actually looks similar (minus the tree).
You can also make out the John Batchelor statue and St John the Baptist Church.
1910
In 2010 The Cow and Snuffers, one of Cardiff's oldest pubs closed its doors and was turned into flats.
Built in the 19th century, the Tudor-style pub, one of the oldest drinking venues in the city and there is a local legend that two time UK Prime Minister Benjamin Disraeli stayed there once.
Even now there is a bust of him above the door which has primroses put on it every April 19 – the anniversary of his death.
Unfortunately there is no evidence that he did actually stay there and he always denied it.
1920
It is almost exactly a century since this picture was taken on Queen Street.
We retain so much beautiful architecture in Cardiff and it is still there - as long as we look up from our phones.
1930
Howell's School - if we made both pictures black and white could you tell the difference?
1940
AG Meek on Albany Road, traded for 100 years. It even survived damage in the war.
It is now a supermarket.
1950
Ah back when Wales played at the Arms Park.
They Wales went on to beat France 20-0 to clinch the championship and the Grand Slam in March 1950.
1960
If you ignore the cars, the wires and the lack of Wok to Walk, St Mary Street is pretty similar!
Another place which looks strange with cars outside was the station.
Until a couple of years ago there was a taxi rang outside the front of Cardiff Central.
1970
The bridge at the top of Bute Street looks pretty similar. Minus the boozers on the side!
The picture below was taken in 1972 and is of Mrs Alice Huntley who has lived at 51 Wimborne Street, Splott, for 48 years
She is watched by her granddaughter Ann, Mrs Huntley has complained about rats that infest her home.
The street no longer exist and was near Moorland Park.
1980
The from front of Woolworth may have changed but there are still some things that remain the same.
If you look really closely you can see the pillar from the bank next door on the right of the picture.
The Calder shop was a mainstay of Cardiff's Queen Street.
Alexander Calder originally set up the business opposite Cardiff Castle before moving to Queen Street in 1920 as a gentleman's outfitter before expanding in 1975 to include ladies fashions and a coffee lounge.
It has now been replaced by the sparely populated Capitol building.
1990
It seems like money has been spent on logos and branding at Cardiff airport over the last thirty years.
At least they made a saving by keeping the post box.
There was violence in Cardiff during the early 1990s during the Ely bread riots.
The trouble was sparked after an argument between two shopkeepers.
This picture shows riot police on Wilson Road in 1991.
