Qal'at Bani Hammad
fortified palatine city in Algeria
Qal'at Bani Hammad (Arabic: قلعة بني حماد), also known as Qal'a Bani Hammad or Qal'at of the Beni Hammad (among other variants), is a fortified palatine city in Algeria. Now in ruins, in the 11th century, it served as the first capital of the Hammadid dynasty. It is in the Hodna Mountains northeast of M'Sila, at an elevation of 1,418 metres (4,652 ft), and receives abundant water from the surrounding mountains. The site is near the town of Maadid (aka Maadhid), about 225 kilometres (140 mi) southeast of Algiers, in the Maghreb.
In 1980, it was inscribed as a World Heritage Site by UNESCO under the name Al Qal'a of Beni Hammad, and described as "an authentic picture of a fortified Muslim city".
The town includes a 7-kilometre (4 mi) long line of walls. Inside the walls are four residential complexes, and the largest mosque built in Algeria after that of Mansurah. It is similar in design to the Grand Mosque of Kairouan, with a tall minaret, 20 metres (66 ft).
Excavations have brought to light numerous terracotta, jewels, coins and ceramics testifying to the high level of civilization under the Hammadid dynasty. Also among the artifacts discovered are several decorative fountains using the lion as a motif.

Why this record matters
The phrase “fortified palatine city in Algeria” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q500367. VIAF identifies the subject as 311738661. Authority coordinates are 35.814, 4.793. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1980.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
