In the fifth year of Rehoboam, the Kingdom of Solomon split. The ten northern tribes set up the Kingdom of Israel under Jeroboam. To prevent the people from going to Jerusalem during the feast days, Jeroboam made two golden calves and put them in temples, one in Bethel and one in Dan (1Kings 12:28,29). The temple in Bethel has not yet been found, but the one in Dan survived and has been excavated.
In this reconstruction drawing, we see the complete temple for the golden calf in the centre of the courtyard, with a stairway leading up to it. In front of the temple was an altar, while other rooms were arranged around the sanctuary.
