In 1935 the colonial anthropologist G. I. Jones photographed a startling sight near the village of Nsude in the Udi highlands of south-eastern Nigeria: ten circular stepped pyramids of moulded clay, arranged in two parallel rows of five, the tallest around 5.5 metres high with basal tiers some 18 metres round. Built by the Igbo community as shrines to the tutelary deity Uto — associated with the earth goddess Ala — each was topped with a stick marking the god's dwelling place. Being unfired clay, the structures have since weathered away almost entirely, surviving mainly in Jones's photographs, now held at Cambridge.

The mainstream view

What archaeology says

The documentary record for the Nsude pyramids is thin but coherent. Besides Jones's 1935 photographs, the ethnographer George Basden recorded a visit and local accounts, and Kenneth Murray, pioneer of Nigerian heritage preservation, described ten solid mud pyramids in two rows on open ground outside the village, each roughly circular, stepped in five diminishing tiers, and crowned with a stick representing the residence of the god. Oral tradition holds that each of the ten quarters, or extended family groups, of Nsude built and maintained one pyramid.

Scholars of Igbo religion situate the monuments within well-attested practice: monumental mud shrine-building, the cult of Ala/Uto as earth deity and moral guardian, and the cyclical renewal of sacred architecture. Because unfired clay erodes within decades, the pyramids Jones photographed were almost certainly rebuildings of earlier versions — meaning the tradition could be considerably older than any surviving fabric, though no excavation has ever tested the site's antiquity.

The mainstream lament is neglect rather than mystery. The structures were never protected, and today only remnants and the memory of elders mark the spot. Nigerian heritage advocates, journalists and Enugu State officials have periodically called for reconstruction and for archaeological investigation, which has yet to happen at any scale.

The alternative view

What the skeptics propose

The Nsude pyramids sit at the centre of a lively Afrocentric and alternative discourse about deep Igbo antiquity. Popular accounts frequently assert that they are thousands of years old and echo, or even precede, the stepped pyramids of Egypt and the mud-brick deffufas of Nubia — the visual rhyme with Djoser's step pyramid at Saqqara and with Kushite architecture is striking, and diffusionists in both directions have used it: some argue Nile Valley influence travelled to West Africa, others that the movement ran the other way.

The most developed scholarly-adjacent case came from the Nigerian professor Catherine Acholonu (1937-2014), who in works such as The Gram Code of African Adam (2005) and They Lived Before Adam (2009) argued that south-eastern Nigeria preserves traces of an extremely ancient civilisation, reading the Nsude pyramids, the Igbo-Ukwu bronzes and local rock inscriptions as fragments of a forgotten African motherland of world culture. Her methods — heavily linguistic and esoteric — are not accepted by archaeologists, but she gave the pyramids a prominence academia never had.

More measured alternative voices simply point out that the null hypothesis is untested: no radiocarbon dates, no stratigraphy, no survey has ever been attempted at Nsude. Until someone excavates, they argue, confident statements that the pyramids are recent are as unfounded as claims that they are primordial — and the burden sits awkwardly on a discipline that ignored the site for ninety years.

Key evidence cited

Striking formal resemblance to Djoser's step pyramid and Nubian deffufa architecture
Catherine Acholonu's published arguments for extreme antiquity of Igbo civilisation
The sophistication of nearby Igbo-Ukwu bronzes (9th century AD) showing deep regional complexity
A rebuilding tradition that could, in principle, extend the design back many centuries
Complete absence of excavation, leaving the tradition's true age unmeasured

Genuinely open questions

How old is the pyramid-building tradition at Nsude — decades, centuries, or more?
Were similar stepped shrines once widespread across Igboland and lost undocumented?
Is there any historical connection, however indirect, between West African and Nile Valley stepped monuments?
Can the site still yield stratigraphy for excavation, and will it ever be protected or reconstructed?

Worth knowing

Each of Nsude's ten extended-family quarters built its own pyramid — a neighbourhood monument scheme photographed just once before the rains took it back.
