In addition to the analysis of written sources and the study of maps, another source of information on the historical visual character of towns is pictorial works, i.e., vedutas and, since the 19th century, photographs. Photographs and postcards capturing public spaces and buildings that no longer exist are essential for the purposes of historical topography. Studying and comparing these materials might contribute to reconstructing past roads and urban developments, locating buildings, and defining their visual aspects and purpose. Despite the fact that photographs are a relatively recent source, one of the pitfalls might be the dating of them.
