The National Library of Ireland has a wealth of incredible photos that have been remastered which are now available on Flickr.
There are thousands available under the creative commons license and in a bid to get you looking through this wonderful and free resource, we thought we'd pick 23 of the best that showcase the changes that Dublin has overgone.
Amazing how much the city changes in some ways and in other ways it looks exactly the same. An incredible resource that's really worth checking out.

9. Penny farthing
10. Post card brings van to your door
This is Main Street, Rathfarnham.
11. In the eyes of the law...

12. Abbey Street and Sackville Street shelled, rubble remains
The tram passing by was numbered 244. The ads on the tram are for Donnelly's Bacon, Hudson's Super Soap and the Metropolitan Laundry. An ad for Bovril can just be made out on another tram. This was taken in May 1916.

For many years an iconic building in the heart of Dublin, it was torn down much to the dismay of many Dubliners and theatre goers.
