The remains of a Samaritan sacred precinct dating from the mid-fifth century BC have been excavated on the highest point of Mount Gerizim. Tensions had developed between the Jews and the Samaritans when Nehemiah did not allow the Sanballat, the leader of the Samaritans, and other adversaries to help them build the walls of Jerusalem and the Temple Mount. These remains show that a rival temple was built here by the Samaritans. A closed courtyard that could be entered through three gates, was built around the Temple. No descriptions or remains of this east-facing temple have been preserved, but it probably followed the well-known pattern of having a porch in front of the actual sanctuary.
