View looking west at the west end of the west Forum. On the left are three columns (2+1) that are remnants of the Temple of the Emperors Vespasian (A.D. 69–79) and his son Titus (A.D. 79–81).
Behind them, all of the gray tufa stones—the lower wall, and the three gray arches above it, are the remains of the ancient Tabularium—the archive building of ancient Rome. The reddish "modern" structure built on top of it, with three rows of many windows, is the Palazzo Senatorio. Behind the Tabularium and the Palazzo Senatorio is where the Capitoline Hill was/is located.
This side of the Tabularium, and to the right of the Temple of Vespasian and Titus, is where the Temple of Concord was located—the low brown arched brick area in the lower right quadrant of the image.
