Lamidat de Rey-Bouba, Cultural palace complex in North Region, Cameroon.

Lamidat de Rey-Bouba is a palace complex in Cameroon's North Region, built on about five hectares and enclosed by a seven-metre-high earthen wall with six gates. The main wall runs 800 metres and is 1.5 metres thick at its base, tapering to 0.5 metres at the top. Inside are three main buildings serving as the Lamido's audience hall and a distribution hall, plus courtyards, vegetable gardens and quarters for the Lamido and his notables. Large earthen boukarous with thatched roofs serve as granaries and stores.

Bouba Ndjidda, the first known ruler of the lamidat and a native of the Mali region, had the palace built between 1805 and 1808 after settling with his Fula warriors on the banks of the Mayo-Rey. Oral tradition holds that he carried a white flag, a silver drum, a sword and a basket of royal secrets, attributes the lamido still does not travel without. The site was inscribed on UNESCO's tentative World Heritage list on 18 April 2006.

The Lamido rules with a council of dignitaries, the faada, headed by a prime minister, the Wadjiri, alongside ministers of agriculture, commerce and justice. Polygamy is practised by all inhabitants and obligatory for the lamibé, who may marry up to fifty women, choosing wives from different ethnic groups. Divorce is permitted and common.

Access is by poorly maintained dirt tracks; from Garoua the most passable route runs past the north side of the Lagdo Dam. The palace covers about five hectares within a seven-metre earthen wall pierced by six gates, so plan for rough ground and walking between the gates.

The wall's thickness tapers from 1.5 m at the base to 0.5 m at the top, a detail recorded in descriptions of the palace. The oral tradition also names the founder's regalia: a white flag, a silver drum, a sword and a basket of royal secrets, which the lamido still does not travel without.
