As you will see from the modern pictures most of what you are looking at has gone...
The modern photo looks in the opposite direction
Where there was once a railway there is a modern road system and even that bus station has been replaced.
There is the wave sculpture and that big building is The Riverfront theatre.Next to it is the Old Moderator Wharf building -in the old picture-and it is (was?) a restaurant.
All the other old buildings long gone and there is a modern shopping centre at the Southern end of the old picture.
The southern end of the old picture..that prominent building is the Newport Centre..opened in 1985-Elton John played there-and is due for demolition and replacement
