ca. 2nd-4th century, Rome, Italy
A group of international researchers and archeologists, led by Dr. Norbert Zimmermann of the Institute for the Study of Ancient Culture at the Austrian Academy of Sciences in Vienna, in cooperation with Prof. Dr. Marina Döring-Williams of the Institut für Baugeschichte und Bauforschung at the Technical University of Vienna, created this 3D rendering of the Domitilla Catacombs in Rome.
This underground burial chamber, or necropolis, dates back to the second century and remained a popular pilgrimage site through the Medieval Period. The team used sophisticated laser-scan technology to create a three-dimensional "point cloud" of the 15 kilometers of tunnels and chambers. This video shows a short segment of the catacombs.
