Looking at this aerial view of Blackburn from July 1961 you realise how much the town centre has changed in the intervening years.

The railway station (top left) and the cathedral (top centre) remain virtually the only recognisable landmarks from 1961 which remain unchanged today.

Towards the top right of the picture you can see the old market and its much lamented market clock tower on King William Street across the road from Marks and Spencer with its distinctive white frontage.

The uncovered River Blakewater flows into the town centre towards Salford with Penny Street running up from the bottom of the picture. What else can you spot on the photo?
