Solomon's Porch, Portico or Colonnade (στοα του Σολομωντος; John 10:23; Acts 3:11; 5:12), was a colonnade, or cloister, located on the eastern side of the Temple's Outer Court (Women's Court) in Jerusalem, named after Solomon, King of Israel, and not to be confused with the Royal Stoa, which was on the southern side of Herod's Temple.
Titus Flavius Josephus a Jewish historian who lived in Jerusalem during the 1st century CE, and was present at its destruction by the Romans in 70 CE, speaks of the wall and of the cloister or porch that King Solomon built east of the Temple House:
As witnessed by Josephus, the exact dimensions of Herod’s Temple formed a perfect square - a furlong by a furlong on all four sides. On the east wall was a double cloister, porch, which in later times is referred to as Solomon's porch.
The historic writings of Josephus give an eye-witness account to the First and Second Temples, as well as Herod’s Temple, all shared the same fore-mentioned east wall of the Temple complex. The east boundary line of the Temple complex never changed. Josephus was clear that Herod refused to let his builders make any changes in the ancient works of the east wall because of the great expense. Herod allowed the construction of new courts on the north, west and south sides of the Temple but the east wall remained intact and undisturbed.
Not to be confused with Herod's Royal Stoa, a porch, portico, or colonnade on the south wall of Herod's Temple.
The location of Solomon’s First Temple, and Zerubbabel and Herod's Second Temple site, has remained a mystery for almost two thousand years. All were built on the threshing floor bought by King David. Finding the location of Herod’s Temple would help us to locate Solomon’s Porch. The location of the Temple has been a divisive subject. There have been many discrepancies concerning the size of Herod’s Temple complex and where it was situated on the Temple Mount. The historical evidence does not support the idea of the whole Temple Mount as being Herod’s extended courts to the North, West and South, as per the Dome of the Rock platform theories suggest. In these theories Herod's extended Temple courts would be almost triple the size of the furlong by furlong description of the Temple given by Josephus. Once the actual location of the Temple on the Mount is understood then also the location, and size, of Solomon’s Porch/Portico will be revealed.
