What it is
The Peace Memorial Museum is the domed building at Mnazi Mmoja, on the inland side of Stone Town beyond Creek Road. It is the most unusual piece of architecture the British protectorate left in Zanzibar, and it is one of the sites whose current status this page cannot establish.
What it was built as
The Zanzibar Department of Museums and Antiquities records that the museum was built soon after the First World War as a permanent memorial to those who lost their lives in it. It credits the design and construction to J. H. Sinclair, whom it describes as British consul and Resident from 1895 to 1923, assisted by P. C. Harris, the Government Architect. It describes the style as an imitation of two famous buildings, Hagia Sophia and the Taj Mahal.
The building was opened on Armistice Day 1925 by Seyyid Khalifa bin Haroub, Sultan of Zanzibar from 1911 to 1960, who gave it the name Beit el-Amani — the House of Peace.
Sinclair is a recurring name in the town. The advisory body evaluation prepared for the World Heritage inscription records that British colonial architecture in Zanzibar was built under his influence and that he introduced features drawn from the Islamic architecture of Istanbul and Morocco. The evaluation calls him an architect; the department calls him a consul and Resident. Both descriptions appear in the record, and the building is the clearest thing he left behind.
Whether you can go in
That could not be established, and the reason matters. The Department of Museums and Antiquities, which holds this building, has a website that refuses connections outright — as do Zanzibar’s tourism and heritage sites. This page therefore records the managing authority as unreachable rather than concluding that the museum has shut. Those are different things and only one of them can be checked from here.
What the department’s own material showed when it was last reachable was a plan rather than a working display: a description of a Zanzibar museum of art, written in the future tense, covering art in architecture, pottery, basketry, costume and carving in wood, gourd, shell, bone, stone and metal. Whether that display was ever installed is not recorded anywhere this page could reach.
The University of Cape Town’s Zamani Project documented the building in three dimensions, inside and out, in 2008, so a detailed record of it exists independently of its present use. The wider position on Zanzibar’s museums is in the museum tours guide.
The practical advice is short: do not plan a morning around it without checking locally on the day, and do not assume from silence that it is closed.
Common questions
Is the Peace Memorial Museum open?
Unconfirmed. The Zanzibar Department of Museums and Antiquities, which holds it, cannot be reached — its website refuses connections. That is a reason to check locally, not a reason to assume the museum has closed.
What was it built for?
As a permanent memorial to those who died in the First World War. It was opened on Armistice Day 1925 by Sultan Seyyid Khalifa bin Haroub, who named it Beit el-Amani, the House of Peace.
Who designed it?
J. H. Sinclair, recorded by the department as British consul and Resident from 1895 to 1923 and by the World Heritage evaluation as the architect behind Zanzibar’s British-era buildings, assisted by the Government Architect P. C. Harris.
