direct quote from the site: “byzantium 1200 is a project aimed at creating computer reconstructions of the Byzantine monuments located in İstanbul, Turkey, as of year 1200 AD.” The project was partly inspired by Alan Sorrell’s (who is referred to as the master of reconstructional drawing) famous painting of istanbul. Background information can be found here. 54 monuments are listed for remodelling, only 9 of them were incomplete when I last checked it out (i.e. a moment ago). I find it very practical that each reconstruction is accompanied by a map (and very impractical that the map cannot be magnified for a closer look).
