To this day, the Leaning Tower of Pisa is one of the most photographed sights in Italy. In the 1850s, the trained sculptor Enrico Van Lint repeatedly photographed the tower and the other buildings on the Cathedral Square from different perspectives. Under good weather conditions, the exposure times ranged between 20 seconds and 7 minutes, on overcast days up to 18 minutes. In the second half of the nineteenth century—long before the invention of the picture postcard—travellers to Italy could purchase the small-scale prints as souvenirs. This view by Enrico Van Lint is one of the oldest objects in the Städel Museum’s ancient photography collection which, like the photo itself, dates back to around 1850.
