Holy Land Maps
An excellent source of late Medieval and Early Modern maps of the Holy Land, this site includes great images with high resolution. Although the earliest map on the site dates to 1462, several of the maps are in fact reproductions of classical cartographic endeavors (e.g. the site features several 16th-century renditions of Ptolemy’s 2nd-century maps).
