Iaat (Arabic: إيعات also transliterated as Ya'ad, Yaad, Yaat, or Iaad) is a town and municipality located in the Beqaa Valley of Lebanon mostly famous for its Corinthian column. The column stands at 251 meters (59.1 feet) it is installed on a 4 step base. The location of the Pillar is 4 miles (6 km) northwest of the Baalbek ruins, between the towns of Baalbek and Chlifa. At one point a plaque was installed on the northern side of the monument, however it has been removed and no other history is known of the column, which is believed to be a funerary monument. The column is also widely believed in local legend to be related to St. Helena.
George F. Taylor classified it amongst a group of Temples of the Beqaa Valley and noticed that the position of the Iaat column was equidistant between the temples of Baalbek and Qasr el Banat. Whilst technically not being a temple, Taylor suggested that the column might have been placed where it is to mark the site of a great ancient battle. He also noted a cartouche on the sixth cylinder of the column.
