A careful reading of Josephus's writings and years of excavation allowed Ehud Netzer, an archaeologist from Hebrew University, to discover what he considered to be the location of Herod's Tomb, after searching for 35 years. It was above aqueducts and pools, at a flattened desert site, halfway up the hill to the Herodium, 12 km south of Jerusalem—as described in Josephus's writings. In October 2013, archaeologists Joseph Patrich and Benjamin Arubas challenged the identification of the tomb as that of Herod. According to Patrich and Arubas, the tomb is too modest to be Herod's and has several unlikely features. Roi Porat, who replaced Netzer as excavation leader after the latter's death, stood by the identification.
