Rabat Tepe, an ancient site in northwestern Iran near the Little Zab River, reveals insights into two distinct periods from the Iron Age. The primary focus of excavations has been on the layers dating back to the first millennium BC. Notable discoveries at Rabat include a striking pebble mosaic pavement, fortified walls, and various decorative bricks. The site’s size, architectural remains, and uncovered artifacts point to its significant role during the first millennium BC. Through multiple excavation seasons, researchers have gleaned valuable information about the site’s layout and historical eras. Evidence suggests that a thick wall once enclosed the entire area, around 3 meters in width. Artifacts found at Rabat share similarities with those from Qalaichi, a well-known Mannaean site. While initially attributed to Mannaean culture, this association is now under debate. Excavations between 2006 and 2008 unearthed inscribed bricks inscribed with Neo-Assyrian cuneiform script. These findings sparked discussions and identified Rabat with ancient cities like Paddir/Šurdira and Hubushkia, although these identifications face significant challenges. Rabat was an independent religious-royal city-state.
