Basalt hilltop fortress of the Khaybar oasis, conquered by the Muslims in 628.
Qamus Fortress stands on a basalt hilltop within the Khaybar oasis, along the Madinah-Tabuk Highway about 150 kilometres north of Madinah, in Saudi Arabia's Al Madinah region. Khaybar was an agricultural oasis with a prominent Jewish community and a network of fortified strongholds before the arrival of Islam. The Muslims besieged and conquered the oasis in 628 CE (7 AH), shortly after the Treaty of Hudaybiyyah, and Qamus is the best-known of the forts associated with that campaign. It is traditionally linked in Islamic sources with the final stage of the fighting, in which Ali ibn Abi Talib is reported to have played a leading role.
The fortress is built of dark volcanic basalt blocks that match the surrounding lava fields. Its walls follow the contour of a rocky outcrop and overlook the palm groves and the fields of the oasis, giving it a clear defensive advantage. The remains include sections of curtain wall, stone chambers and the bases of towers, although the structure has been much altered by erosion, reuse and rebuilding over many centuries. The overall impression is of a compact, rugged stronghold rather than a monumental castle, and its dating is difficult because parts are likely to be older than the seventh century.
The site is interpreted mainly through signage and local guides, and there is no formal museum on the hill. Archaeological and heritage work in the Khaybar area has been expanding as part of Saudi national heritage programmes, with surveys of the oasis settlements, tombs and rock art. Visitors can walk around the base of the fort and, where the paths are safe, onto the lower terraces, but unstable stones and steep sections mean care is needed.
Entry is free and the site is open during daylight hours. Khaybar is usually visited as a day trip from Madinah, or as a stop on the road to AlUla and Tabuk. Summers are very hot, and winter mornings give the most comfortable conditions. The surrounding oasis, with its date plantations and black lava fields, adds to the visit.

Tips for visiting

- Visit in winter or early morning; the black basalt radiates heat in summer.
- Wear sturdy shoes, as the stonework is uneven and loose in places.
- A local guide adds the story of the conquest, since signage is minimal.
- Carry water and fuel up before leaving Madinah.
When to visit
November to March, in the morning; summer heat on the black basalt is intense.
Accessibility
The fortress is on a rocky hill with uneven basalt surfaces and no formal ramps, so access is difficult for wheelchair users and visitors with limited mobility. Views of the fort can be had from the base.
