 Nevertheless, architectural remnants from the Late Antique period can now be seen thanks to excavation work done by Jordanian and German archaeologists after the site was re-discovered in the early twentieth century. Of all the ruins now unearthed, the octagonal [martyrium][martyrium] is one of the most significant. About the large terrace where the martyrium is currently found, researchers[^Vriezen] say it was completely remodeled from a Roman forum basilica into a Byzantine ecclesiastical compound, with a centralized church, a basilica, and courtyards in the sixth century CE. Martyria such as this were once extremely common in the eastern Mediterranean, though few are still standing today. They were typically used to commemorate a person, a divinity, or an event.[^Grabar]

 The significance of Gadara's octagonal martyrium is the remarkable similarity of its plan to another prominent (although later) building less than 100km away in Jerusalem: the [Dome of the Rock]({{< relref path="dome-of-the-rock.md" lang="en" >}}). Umayyad caliph [ʿAbd al-Malik][abdalmalik] built the Dome of the Rock near the end of the seventh century and it is one of the first — and finest — Islamic monuments in existence. It has a central octagonal plan, a vaulted dome, and an altar featuring a rock (a stone-lined tomb in the case of Gadara[^Amal]), which suggests a commemorative purpose for the building.[^Donner] It is unclear what this building meant to people living in the seventh century, but there is no doubt that an architectural language that was extremely common in the Mediterranean basin in the Late Antique period influenced its construction.[^Grabar]
