SepiaTown is a cultural history project that aims to provide a window to the past by merging photography, geography, and technology, by acting as a forum for institutions and individuals to share and map historical images.

Once they have signed up, users may upload historic images to the site individually or in batches. Each image is given a title, description and keywords, as well as a spatial location represented by a marker on a map.

Visitors to the site can search or browse by using keywords and place-names, or by going directly to the map and clicking on a thumbnail to view images directly.
