This gallery, called simply the Map Room or the Gallery of Maps, was named after the 40 topographical maps of the regions of Italy, and of the Church's possessions that Gregory XIII had painted here
between 1580 and 1583. These maps constitute and extremely important
record of 16th century geography and cartography.
Though the cartographic works of the
Map Room undoubtedly have historic significance, to me the artwork on the ceiling was more visually interesting.
