It was the first building in East Africa to be electrified and featured an elevator, an astonishing innovation in the late 19th century. Its function extended beyond being a royal palace it later became a government office during British colonial rule, a school, and eventually a museum dedicated to Zanzibar’s maritime and cultural history.

Perspectives from Historical and Academic Sources
1. Wikipedia and Academic Analyses
Wikipedia describes the House of Wonders as “the most iconic building in Zanzibar,” highlighting its significance as both a cultural and historical landmark. Its status as part of Stone Town’s UNESCO listing underscores its architectural and political importance.
2. Historical Studies on Zanzibar
In the book “Zanzibar: Gateway to the Indian Ocean”, British historian John Mitchell argues that the House of Wonders was more than just a palace; it was a symbol of the region’s transformation following the abolition of the slave trade, shifting its economy towards legitimate commerce.
3. UNESCO Reports
UNESCO reports emphasize that the building’s structural integrity has suffered due to environmental conditions, particularly high humidity and salt exposure, leading to the deterioration of coral stone and metal frameworks.
4. Media Coverage and Documentaries
A Guardian article describes the House of Wonders as “a mirror reflecting the interconnected histories of East Africa, the Middle East, and Europe,” yet warns that without urgent restoration efforts, the building may be lost to history.

Collapse and Restoration Efforts
In December 2020, a significant portion of the building collapsed, raising alarms about the urgent need for preservation. In response, the Zanzibari government and UNESCO partnered with international organizations to initiate a comprehensive restoration project. The work includes:
- Reconstructing collapsed sections using original coral stone.
- Restoring corroded ironwork to prevent further structural damage.
- Refurbishing wooden balconies and replacing decayed elements with authentic Swahili craftsmanship.
The estimated cost of the restoration runs into millions of dollars, with the aim of reopening the House of Wonders as a state-of-the-art museum that honors Zanzibar’s unique cultural legacy.
