The Via Dolorosa is not one street, but a route consisting of segments of several streets. One of the main segments is the modern remnant of one of the two main east-west routes ("Decumanus Maximus") through the Roman city of Aelia Capitolina, as built by Hadrian. Standard Roman city design places the main east-west road through the middle of the city, but the presence of the Temple Mount along much of the eastern side of the city required Hadrian's planners to add an extra east-west road at its north. In addition to the usual central north-south road ("Cardo Maximus"), which in Jerusalem headed straight up the western hill, a second major north-south road was added down the line of the Tyropoeon Valley; these two cardines converge near the Damascus Gate, close to the Via Dolorosa. If the Via Dolorosa had continued west in a straight line across the two routes, it would have formed a triangular block too narrow to construct standard buildings; the decumanus (now the Via Dolorosa) west of the Cardo was constructed south of its eastern portion, creating the discontinuity in the road still present today.
