Guardian Edinburgh has teamed up with the keepers of Scotland's built heritage archives - the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) - to bring you some fascinating images of the city's past.
But even archives have to grow and change, and that's where you come in. Archivists at RCAHMS want you to directly add your local knowledge to the national collection via their Canmore portal.
Whether from exactly the same angle as our featured shot or from a different perspective, your pictures can help shape the city's history.
There are plenty of pictures of Portobello beach, but do you have one of it looking busier than the shot above?
Our fourth featured area in the series, Portobello saw a boom in beach-trade in the 1860s. It was one of many popular Scottish beaches owing its success to the expansion of the railways and a new phenomenon in tourism: the day-tripper.
A Victorian day at the Scottish seaside was likely to include donkey rides, fish and chips, and a walk along the promenade. The 381-metre-long 'prom' in Porty was built in 1870, complete with a pavilion and bandstand.
Find out more about Portobello's history and see more pictures of it on Canmore.
