Vatican Museum's "Gallery of Maps"

I recently visited the Vatican Museums in Rome, Italy. The "Gallery of Maps" in particular left quite an impression of me. Dating from the late 1500s, its frescoes have brilliant, dazzling colors and the detail is breathtaking. The maps have beautifully decorated legends and descriptions of the cultures of the people who lived there. The above are pictures which I personally took.

From Wikipedia:
"Topographical maps of the whole of Italy, painted on the walls by friar Ignazio Danti of Perugia, commissioned by Pope Gregory XIII (1572–1585). This gallery is...120 m long. It took Ignazio Danti three years (1580–1583) to complete the 40 panels. The decorations on the vaulted ceiling are the work of a group of Mannerist artists...These maps constitute an extremely important record of 16th century geography and cartography."
