One site, two names
The former slave market and Christ Church Anglican Cathedral are the same place. The cathedral was built on the ground where the market stood, and the conservation authority’s own list of completed works names the project “Restoration of Anglican Church (Old Slave Market) 2017–2018”, treating the church and the market ground as one site. This page does the same, because writing the two apart would mean setting down the same material twice.
It is the most visited historical site in Stone Town. It is not a sight, and this page does not treat it as one.
What the record establishes
UNESCO’s description of the World Heritage property names Christ Church Anglican Cathedral among the town’s major buildings, commemorating David Livingstone’s work against the slave trade and built on the site of the last slave market. One of the three criteria under which the town was inscribed rests directly on this: Zanzibar’s symbolic importance in the suppression of slavery, as one of the main slave-trading ports in East Africa and as the base from which the campaign against it was run.
The advisory body evaluation prepared for the inscription describes the cathedral as in part a monument commemorating the abolition of the slave trade in the Sultan’s dominions. Its foundation stone was laid in 1873 and it was consecrated in 1903. It was named after Canterbury Cathedral. The plan is basilican, with what the evaluation calls an unusual combination of Perpendicular Gothic and Islamic detail — the building is worth reading as architecture as well as as a memorial, and the fusion in it is the same fusion the town as a whole was inscribed for.
The Stone Town Conservation and Development Authority restored the building between 2017 and 2018.
What is contested
The underground chambers shown to visitors as slave-holding cells are the subject of a live academic dispute, set out in the Stone Town guide, which records a 2020 study arguing that the site has been shaped as a place of memory at the expense of historical accuracy and citing an 1892 map that labels the location Kwa Kimoto with no mention of chambers at all.
Two further points belong here rather than there. First, the specific figures that circulate about the chambers — how many there were, how many people were held in each, and what the fittings inside them were for — are not repeated on this page. No source has been established for them, and a site whose authenticity is disputed is not a place to pass on unsourced detail. Second, none of that touches what is documented. Zanzibar’s role in the Indian Ocean trade is established beyond argument and is written into the town’s World Heritage inscription. The uncertainty is about one set of rooms, not about the history.
Visiting
The cathedral and the exhibition beside it stand on their own, and a thoughtful visitor can manage without a guide. The exhibition is the part that carries the documented history.
Dress as you would for any place of worship, keep photography to what the site permits, and treat the pace of the visit accordingly. The wider history — the shape of the trade, the sites at Mangapwani and on the mainland, and what is documented against what is repeated — is in the slave trade history guide.
Common questions
Are the slave market and the Anglican cathedral the same place?
Yes. The cathedral was built on the site of the last slave market, and Zanzibar’s conservation authority treats the two as a single site in its own project records.
Are the underground chambers authentic?
Contested. A 2020 study argues the site has been constructed as a place of memory at the expense of historical reality, and cites an 1892 map naming the location Kwa Kimoto with no mention of the chambers. Their authenticity is disputed within Zanzibar as well.
When was the cathedral built?
The foundation stone was laid in 1873 and the building was consecrated in 1903. It was named after Canterbury Cathedral and combines Perpendicular Gothic with Islamic detail.
Do I need a guide?
Not for this site. The exhibition carries the documented history and stands on its own, and a confident narrative is not the same thing as an accurate one here.
