The House of Wonders, or Beit al Ajaib, is the largest building in Stone Town and has been closed to visitors since part of it collapsed in December 2020. Tours now view it from the seafront and the Old Fort courtyard while restoration continues. Built in 1883 for Sultan Barghash bin Said on Zanzibar’s waterfront, the House of Wonders is a central component of the UNESCO listed Stone Town of Zanzibar.
It is worth saying plainly at the start, because a lot of guidebooks have not caught up: you cannot go inside. What you can do is understand what you are looking at, which turns a boarded up facade into the most informative object on the waterfront.
What a House of Wonders Tour Looks Like Today
Every Stone Town walking tour stops here, and the stop lasts longer than you might expect for a closed building. Guides use the exterior to explain the whole arc of Zanzibar’s 19th century, because this single structure sits at the centre of it.
You stand on Mizingani Road with the sea at your back. The north west corner, the section that came down, is hoarded off and visibly missing. The clock tower that once rose above the entrance is gone. What remains is a three storey block roughly fifty metres on each side, wrapped on every floor by tiers of cast iron verandas, with the tallest carved doors in Zanzibar set into the seaward face.
Photography from the street and from the neighbouring Old Fort courtyard is unrestricted. Access to the interior, the terraces and the museum is not, and nobody offering to get you in has the authority to do so.
Anyone approaching you near the seafront offering interior access to the House of Wonders is running a scam. The building is a live structural site. Book through your hotel or a licensed guide and expect an exterior visit only.
Sultan Barghash and the Building of Beit el Ajaib
Barghash bin Said, the second Sultan of Zanzibar, built six palaces during his reign, and this was the ceremonial one. It went up in 1883 on the site of an earlier 17th century palace belonging to the Zanzibari queen Fatuma, which tells you the plot had been the seat of power on this stretch of coast long before the Omanis arrived.
The building was never a residence in the ordinary sense. It was designed as an official reception hall and ceremonial palace, the place where the Sultan received envoys, held court and demonstrated to visiting traders that Zanzibar was not a provincial outpost. Barghash had moved among the great trading capitals of the Indian Ocean, and the scale of the building was an argument.
Context matters here. Barghash was the same Sultan who signed the 1873 treaty abolishing the slave trade under British pressure. The wealth that raised this building came from cloves and from the trade in human beings, and any honest tour of the seafront says so.
Why It Was Called the House of Wonders
The name is literal. Beit al Ajaib was the first building in Zanzibar to be fitted with electric light, and the first anywhere in East Africa to contain a lift. To a population that lit its houses with oil lamps, a building that glowed after dark and carried people upward without stairs was exactly what the name says.
It also carried a clock tower, which made it the timekeeper for the waterfront and the port. The cast iron columns and balustrades were shipped in and assembled on site, a technique that let the builders wrap all three floors in deep shaded verandas without heavy masonry. Those verandas are the reason the building reads as light rather than fortress like, which was the point given what stands next door.
At its full height the structure reached around thirty seven metres. After the collapse it stands closer to twenty nine.
The Anglo Zanzibar War and the Palace Complex
In August 1896 the palace complex on this waterfront was shelled by British warships during the conflict that followed a disputed succession. The bombardment lasted well under an hour and is widely recorded as the shortest war on record. Beit al Ajaib was damaged and subsequently rebuilt, and the neighbouring buildings on the seafront were destroyed outright.
This is why the waterfront reads as a sequence rather than a single palace. The Old Fort predates everything around it. The House of Wonders sits at the centre. The Palace Museum, Beit el Sahel, stands a short walk north and served as the Sultans’ actual residence. Any seafront heritage tour covers all three together, and only the fort is currently open in full.
The Museum of History and Culture Before the Closure
From 2000 the building housed the Museum of History and Culture of Zanzibar and the Swahili Coast, which occupied the ground and upper floors around the central atrium. The collection covered Indian Ocean trade, Swahili material culture, the dhow trade, the clove economy and the sultanate period, with a reconstructed mtepe sailing vessel standing in the central hall.
Before the revolution reshaped the islands in 1964, the building had served the sultanate. Afterwards it became the headquarters of the Afro Shirazi Party, and it stayed in political use for decades before the museum took it over. Zanzibar’s tourism ministry estimated at the time of the collapse that a large majority of visitors arriving on the island came at least partly for this building, which gives some sense of what the closure meant locally.
A building that housed a sultan, a political party and a national museum in the space of a single century. Not many facades on the Indian Ocean have worked that hard.
The 2020 Collapse and the Restoration Project
On Christmas Day 2020 the north west corner of the building came down. Two workers were killed and four were rescued from the debris. The structure was in the middle of a major rehabilitation programme funded by Oman’s Ministry of Heritage and Tourism, valued at around ten billion Tanzanian shillings, and work had been suspended earlier that year during the pandemic. An initial investigation pointed to failures by the contractor handling the restoration.
UNESCO’s World Heritage Centre responded immediately, and its office in Dar es Salaam agreed emergency measures with the Zanzibar government in January 2021. A survey team documented the surviving structure in detail using laser scanning so that reconstruction could work from an accurate record. Oman subsequently pledged further funding, and the scope of work was rewritten to cover consolidation, reconstruction, restoration and rehabilitation rather than the lighter refurbishment originally planned.
Work continues. Visitors who have seen the site in recent years describe it as stabilised rather than visibly progressing, which is normal for heritage projects of this complexity on a porous coral stone structure in a marine climate. No reopening date has been confirmed. Check locally before travelling if this specific building is your reason for visiting.
Combining Beit el Ajaib With a Stone Town Seafront Tour
Because the interior is closed, the building works best as one stop on a wider Stone Town tour rather than a destination on its own. The natural circuit runs along Mizingani Road, taking in the Old Fort with its free courtyard, workshops and amphitheatre, then the House of Wonders exterior, then north to the Palace Museum, then the Old Dispensary with its carved balconies and stained glass, and finally down into Forodhani Gardens for the evening food market.
That loop takes an unhurried two hours and covers the entire sultanate period on foot. Add the Anglican Cathedral and the slave market chambers at Mkunazini and you have a full morning, at which point you have seen the things that put Stone Town on the World Heritage List.
Photographing the House of Wonders on a Waterfront Walking Tour
The building faces roughly west across the channel, which means late afternoon light hits the seaward facade directly and the verandas throw deep shadow lines across it. That is the hour photographers want. Morning light leaves the front flat and backlit.
Three vantage points work. From the sea wall in Forodhani Gardens you get the full width with palms in the foreground. From the raised sections of the Old Fort courtyard you can shoot the flank at an angle that shows the depth of the verandas. From a rooftop terrace in the surrounding lanes you get it against the roofline and the water, which is the shot that most people are actually after. Several restored merchant houses open their terraces to non guests in the late afternoon.
Getting to the House of Wonders and When to Visit
Beit al Ajaib stands on Mizingani Road on the Stone Town seafront, immediately north of the Old Fort, in Zanzibar City on Unguja island. From the airport it is a fifteen to twenty minute drive. From the ferry terminal it is a short walk south along the waterfront.
The dry months from June to October give the most reliable weather for walking the seafront, along with January and February. April and May bring the long rains, and heavy afternoon downpours make an exterior focused visit far less rewarding. Late afternoon is the best hour of any day, both for light and because the seafront fills with local families before sunset.
Frequently Asked Questions About the House of Wonders
How much does it cost to visit the House of Wonders?
Nothing at present, because the building is closed and viewing is from the public street. When the museum was operating, entry ran at roughly $5 to $6 per person. The adjacent Old Fort is free to enter. Guided Stone Town walking tours that include the seafront cost around $20 to $40 per person for a group departure, and the Old Slave Market and Anglican Cathedral site charges about $5.
When will the House of Wonders reopen?
There is no confirmed date. Restoration funded by Oman and coordinated with UNESCO has been under way since the 2020 collapse, with the scope expanded to include reconstruction alongside repair. Progress on coral stone heritage buildings of this size is slow. Ask locally or check with your operator shortly before travelling.
What happened to the House of Wonders?
The north west corner and the clock tower collapsed on 25 December 2020 while the building was undergoing a major restoration that had been paused earlier that year. Two workers died and four were rescued. An initial inquiry found fault with the contractor carrying out the works. The building had already suffered an earlier partial collapse before that programme began.
Why is it called the House of Wonders?
Because it was the first building in Zanzibar with electricity and the first in East Africa with a lift. Both were unheard of in 1883 on the Swahili coast, and the Swahili name Beit al Ajaib translates directly as house of wonders.
Is it worth visiting if you cannot go inside?
As part of a wider seafront tour, yes. It anchors the story of the sultanate, the clove trade and the abolition of slavery in one place, and a good guide will use it that way. As a standalone destination it is a fifteen minute stop at a hoarded facade, so build it into a Stone Town circuit rather than travelling in specially for it.
What else is worth seeing nearby?
The Old Fort next door, free and open daily with craft shops and an amphitheatre. The Palace Museum a short walk north along the seafront. The Old Dispensary, one of the most finely decorated buildings in the quarter. Forodhani Gardens for the evening food market. The Anglican Cathedral and slave market chambers at Mkunazini, about ten minutes inland on foot.
Closures and restoration work change what is possible in Stone Town more often than published guides reflect, and turning up to a boarded facade you had planned a day around is a poor way to spend a morning. Holidays To Zanzibar runs guided seafront and heritage tours with licensed Zanzibari guides and keeps track of what is genuinely open week to week.
