There is a rock on a hill in Jerusalem that the tradition calls the Even ha-Shetiya - the Foundation Stone. The rabbis taught that the world was created from it outward. The High Priest stood on it once a year, on Yom Kippur, and spoke the Name that was otherwise unspeakable. The Holy of Holies was built over it, and then the Second Temple, and then - after two destructions and six centuries of changing rulers - something else rose above it. In 691 CE, a golden dome went up over that rock, and it has not come down since.
The caliph who built it was Abd al-Malik ibn Marwan, fourth ruler of the Umayyad dynasty and a man with an acute sense of political theatre. The Islamic conquest of Jerusalem had happened in 638 CE under Omar ibn al-Khattab - a relatively undramatic handover, by the standards of the city's history. But possessing a city and stamping your civilisation on it are different acts. Abd al-Malik chose the highest, most sacred ground in Jerusalem, the platform the Romans had left intact even after destroying the Temple, and he built the most sophisticated structure in the Islamic world on it. The message was not subtle. It was not meant to be.
The record
The Dome of the Rock was completed in 72 AH (691-692 CE) according to its original foundation inscription, which runs in a mosaic band around the inner octagonal arcade. The inscription is one of the oldest surviving dated texts in the Arabic language and includes a direct theological challenge to Christian doctrine - "God has no associate" - along with praise for Jesus as a prophet but not as divine. The building was constructed under Abd al-Malik ibn Marwan and the inscription names him as patron, though the Abbasid caliph al-Ma'mun later had his own name substituted in the inscription (c. 831 CE) while leaving the original date, which preserved the correct Umayyad attribution for modern scholars. The structure's architectural measurements, inscription texts, and construction date are documented in K. A. C. Creswell, Early Muslim Architecture, vol. 1 (Oxford, 1932; revised 1969), the foundational scholarly study of the building.
What Abd al-Malik built was not a mosque. It is a shrine - a maqam, a place of standing - and its internal geometry is organised around the rock itself, which pilgrims could walk around on the ambulatory beneath the dome. The plan is octagonal: an outer octagon, an inner octagon, and at the centre the great dome, 20 metres in diameter, rising 35 metres above the rock. The mosaics that line the inner arcade are among the finest Byzantine-era craftsmen produced - because they were Byzantine craftsmen, or craftsmen trained in that tradition, hired by an Umayyad patron to do in Jerusalem what their predecessors had done in Ravenna and Constantinople. Vine-scrolls, jewelled crowns, Byzantine imperial regalia - all present, all stripped of human or animal figures, repurposed for a new theological purpose. The building is a conquest made in tesserae.
The record
The rock beneath the dome is almost certainly the site of the debir - the inner sanctuary, the Holy of Holies - of the First and Second Temples. The Byzantine-era pilgrim accounts and the Mishnah tractate Yoma (chapter 5) both describe the Foundation Stone as the surface on which the Ark of the Covenant rested, and where the High Priest placed the incense pan and the blood of the sacrifice on Yom Kippur. The Mishnah records that after the Ark's disappearance (traditionally at the Babylonian destruction, 586 BCE), the stone remained, raised three finger-breadths above the sanctuary floor, and was called the "Shetiyah" - from the root meaning "foundation" or "drinking in." The identification of the rock with the Temple's inner sanctuary is accepted by the overwhelming majority of archaeologists and historians, including Meir Ben-Dov, the lead archaeologist of the Temple Mount excavations conducted under Benjamin Mazar, 1968-1978 (Meir Ben-Dov, In the Shadow of the Temple, Jerusalem, 1985).
For the Jewish community, the completion of the Dome of the Rock was an event with no clean category. The Mount had been in ruins since 70 CE - Byzantine Christian rulers had left it deliberately desolate, a proof-text for their theological argument. The early Islamic rulers had actually permitted Jews to pray on the Mount again; there are accounts of Jewish settlement near the Temple platform in the first decades of Arab rule. The Dome's construction did not expel Jews from the city - it announced, in domed gold, who now held sovereignty over the holiest ground in the world. That is a different thing from persecution. It is the older and more enduring kind of statement: this is ours now, and we have built something that will outlast argument.
The record
The gold dome visible today is not the original. The Dome of the Rock's covering has been repaired, re-clad, and replaced multiple times over thirteen centuries. The modern dome is aluminium alloy coated with gold - 80 kilograms of gold leaf applied during a restoration funded by King Hussein of Jordan in 1993-1994 at a personal cost of approximately US$8.2 million. The exterior tiles on the octagonal drum are Ottoman-era replacements, commissioned by Suleiman the Magnificent in 1545 CE to replace the original Byzantine-style mosaics that had deteriorated. The building's structural form - octagonal drum, circular drum, and hemispherical dome - has remained essentially unchanged since 691 CE. Full conservation history is documented in the Aga Khan Trust for Culture's survey of the Haram al-Sharif (Jerusalem, 2005) and in Robert Hamilton, The Structural History of the Aqsa Mosque (Jerusalem, 1949).
The dome is thirty-five metres high. From the Jewish Quarter, from the Mount of Olives, from the roof of any building in the Old City, you cannot not see it. Every generation of Jews who stood at the Western Wall in the centuries after 691 stood with that gold dome in their sightline - praying toward the Foundation Stone beneath a structure they did not build, over a platform they did not control. The tradition found its answer in the Lamentations and the Psalms: it maintained memory more durable than stone. That the stone should still be there, that the rock should still be there, that the hill should still be there, visible and identifiable - that too is a kind of answer. The world did not take the address.
The Dome of the Rock is one of the oldest surviving Islamic buildings in the world, and it sits on top of one of the oldest sacred sites in human memory. It is both things at once, and there is no resolution available. What there is: a rock, a hill, a name for the rock, a community that has carried that name for three thousand years, and a dome that catches the light at evening and turns it gold. History stacks its layers and leaves them for us to read.
