These 18,000 historical photographs, from the London Metropolitan Archives and the Stadsarchief Antwerpen (State Archives of Antwerp), date from 1840 to the present. Serious design flaws make navigating this website and finding images difficult, but it has the potential to be an invaluable resource for historians, students, and teachers.
