The images show how Market Square has changed over the last century, and offer a contrast to the latest facelift and new centrepiece that is currently being worked on as part of the "Square Routes" scheme that includes a huge improvement to Penny Street, where work is still in progress, and will include the return of the famous horseshoe to "Horsehoe Corner" (on the corner of Market and Penny Street) very soon.
To complement the exhibition, there will be further displays from Lancaster's library and museum archives to illustrate the wide range of local businesses that have been part of the Market Square's history.
The archives also include records of the many celebrations that have taken place in the square over the past 100 years.
The event is funded by the Friends of Lancaster Library, a local voluntary group that helps with many of the events and activities taking place at the library.
Anna Haywood, a library officer at Lancaster, said: “This brilliant event showcases the rich heritage of this historic city. We're very grateful to the Friends for their generosity and hard work helping to bring it all together.
“Visitors to the library will be able to see the transformation Lancaster has undergone over many years and compare that to the future plans.
“We'd also like thank the residents of Lancaster for their valuable support, which has once again shown the wonderful community spirit that we have here in the city.
The exhibition coincides with 'Lancaster Unlocked', a city-wide event celebrating Lancaster's history.
Anyone who has photographs that would be suitable for the exhibition is welcome to contact the library or the Friends of Lancaster Library.
Lancaster City Museum also has a display about the history of the Old Town Hall, now the museum. Staff are keen to hear people's memories or see their photographs.
Lancaster Library is part of Lancashire County Council's library service.
