Egypt's tourism and antiquities ministry announced on 4 July 2026 the excavation of a Byzantine-era city in the Dakhla oasis, a site in the New Valley province roughly 750 kilometres southwest of Cairo, alongside a separate cache of 18 ancient tombs at Marina el-Alamein on the Mediterranean coast — twin finds that together extend the archaeological map of Roman-period Egypt at both its desert and coastal margins.

The Dakhla City

The mission, chaired by Mahmoud Massoud, uncovered a settlement whose street plan conforms to classical urban conventions: north–south thoroughfares intersected by east–west streets opening into public squares. A basilica-style church, dated to the mid-fourth century, anchors the civic core, positioned to overlook the main arteries. On the settlement's periphery, remains of two watchtowers were identified, and a deep defensive moat was traced around a heavily fortified residential precinct whose structures retain thick outer walls, reception halls, and vaulted roofing — The Guardian reports the overall city dates to the fourth century CE.

One structure carries a specific identity: the house of Tisous, a church deacon, assigned to the second half of the fourteenth century of the Common Era and interpreted as a domestic worship space predating the basilica's construction. The sequence — house church giving way to formal basilica — tracks a well-documented pattern in early Christian communities across the eastern Mediterranean, where private oratories served congregations until institutional resources permitted purpose-built liturgical architecture.

The numismatic and ceramic evidence sharpens the chronology considerably. Gold coins recovered from the site are attributed to the reign of Constantius II (337–361 CE), giving a tight terminus post quem for at least one occupation phase. Bronze coins bearing Byzantine imperial portraits alongside Latin inscriptions and Christian iconography supplement the gold finds. Approximately 200 ostraca — pottery sherds inscribed with records of commercial transactions, personal correspondence, and daily-life notations — add a documentary layer that coins alone cannot provide. Bread ovens, kitchens, and stone grinding tools complete the picture of a functioning urban economy rather than a purely administrative or military outpost.

Hisham el-Leithy, secretary general of Egypt's supreme council of antiquities, and Diaa Zahran, head of the Islamic, Coptic and Jewish antiquities department, are associated with the announcement. The Dakhla oasis is already listed on UNESCO's tentative World Heritage list, a status that frames any significant discovery there within an ongoing nomination process — fresh material of this scale will inevitably feed into Egypt's dossier for full inscription.

The broader significance of Dakhla as a Byzantine site lies in what it says about the administrative reach of the late Roman empire into the Egyptian interior. The Western Desert oases — Dakhla, Kharga, Farafra — functioned as nodes in a trans-Saharan route network and as agricultural hinterlands provisioning Nile Valley centres. A city of this physical complexity, complete with monumental religious architecture and defensive infrastructure, argues for a settlement of genuine regional consequence, not a frontier waystation.

Marina el-Alamein

The second announcement concerns Marina el-Alamein, the site excavated since 1986 and identified by scholars as the ancient Greco-Roman port of Leukaspis, founded in the second century CE and active into the fourth. Mission chief Eman Abdel-Khaliq's team added 18 tombs to the site's tally — 11 rock-cut and 7 surface limestone-built — bringing the total documented at Marina el-Alamein to 48.

Among the new finds: a granite sarcophagus measuring 2.5 metres in length containing skeletal remains, and fragments of a plaster sphinx statue recovered in its proximity. Four gold pieces recovered from the mouths of some of the interred reflect the "golden tongue" funerary practice, in which a gold foil or coin was placed in a deceased person's mouth to facilitate passage into the afterlife — a rite documented across Greco-Roman Egypt and attested at multiple Delta and coastal necropoleis.

The Marina el-Alamein finds are less architecturally dramatic than Dakhla but are archaeologically coherent with the site's established Hellenistic-Roman stratigraphy. Each additional tomb expands the demographic and ritual dataset for Leukaspis, a port whose trade connections presumably extended across the eastern Mediterranean during the height of Roman commercial activity.

Taken together, the two announcements — separated by several hundred kilometres and two distinct archaeological traditions — reflect the sustained output of Egypt's domestic excavation programmes, which have accelerated ministerial announcements of major finds over the past decade as the country works to leverage heritage assets for tourism and international profile. The ostraca corpus from Dakhla in particular, if it yields legible Greek or Coptic texts, could generate primary-source material of lasting scholarly value well beyond the architectural record.
