The "way" begins here.  Montefiore makes it clear that this is very unlikely to be the path taken by Jesus to his crucifixion.

Via Dolorosa

The Via Dolorosa (Latin,"Way of Grief", "Way of Suffering" or simply "Painful Way") is a street, in two parts, within the Old City of Jerusalem, held to be the path that Jesus walked, carrying his cross, on the way to his crucifixion. The winding route from the Antonia Fortress west to the Church of the Holy Sepulchre — a distance of about 600 metres (2,000 feet) — is a celebrated place of Christian pilgrimage. The current route has been established since the 18th century, replacing various earlier versions. It is today marked by nine Stations of the Cross; there have been fourteen stations since the late 15th century,^[1] with the remaining five stations being inside the Church of the Holy Sepulchre.
