Khamis Mosque, Mosque in Bilad Al Qadim, Bahrain

Khamis Mosque stands in Bilad Al Qadim with two identical twin minarets visible from Shaikh Salman Road. The present building has a flat-roofed prayer hall on wooden columns, and a later section of roof rests on arches over thick masonry piers dated to 1339. A limestone mihrab slab found during restoration carries verses 34–35 of Surah 21.

The Khamis Mosque is believed to have been founded as early as 692 CE, during the era of the Umayyad caliph Umar II, though an inscription found on the site points to a foundation in the 11th century. It was rebuilt twice, in the 14th and 15th centuries, when the two minarets were constructed; one source attributes the first minaret to the Uyunids and the second, two centuries later, to the Usfurids. The building was partially restored in recent times.

The mosque takes its name from a Thursday market that operated here for centuries as a gathering place. This location served as a center where merchants and residents came together regularly.

The site opens daily from 9 AM to 5 PM, though it closes on Fridays. It sits along Sheikh Salman Highway, making it accessible to visitors arriving by car.

The limestone mihrab slab found during restoration is thought to date from the 12th century. Its two inscribed verses, 34 and 35 of Surah 21, are normally carved on gravestones, not in prayer halls. The slab is kept at the site.
