Zanzibar’s Stone Town — the historic core of Zanzibar City on the western coast of Unguja Island, a UNESCO World Heritage Site (2000), 2.5 sq km of narrow alleyways, carved wooden doorways, coral-stone merchant houses, and the social architecture of an Indian Ocean trading entrepôt that was simultaneously an Arab sultanate capital, a British colonial administrative centre, a slave trade hub (Zanzibar was the centre of the East African slave trade until British abolition pressure ended it in 1873), and an Indian merchant community — is one of East Africa’s richest urban heritage environments. This guide provides a walking tour of Stone Town’s essential sites for 2025 visitors, with navigational detail for independent walkers and an honest assessment of which sites reward the most time.
The Old Fort (Ngome Kongwe)
Start at the seafront: the Old Fort (Ngome Kongwe, built 1699 by the Omani Arabs to replace a Portuguese chapel that had stood on the same spot, restored in 1995) is Stone Town’s most accessible historic landmark — directly on the seafront promenade (Forodhani Gardens area), with a large circular arena inside the fort walls that hosts the nightly Forodhani Street Food Market. Entry: free. The fort houses artisan craft workshops, a small amphitheatre for evening cultural events, and a rooftop terrace with good views of the seafront. Walk south from the fort along the waterfront road (Benjamin Mkapa Road) for 200 m to: the House of Wonders (Beit el Ajaib — the largest building in 19th century Stone Town, built 1883 for Sultan Barghash, the first building in Zanzibar with electric lights and an elevator). The House of Wonders currently under renovation (2024–2026) — exterior viewing only.
The Slave Market Memorial
The Anglican Cathedral and former slave market (Mkunazini area, 5-minute walk from the Old Fort inland from the seafront): built 1873–1880 by the Anglican Church on the exact site of the last active slave market in Stone Town (the market was closed in 1873 following British pressure on Sultan Barghash). The memorial underground chambers (the actual market holding pens where enslaved people were kept before sale, preserved as a memorial) are the most historically significant and most sobering site in Stone Town — the concrete chambers can hold approximately 75 people per cell and the conditions of confinement (no light, no sanitation, minimal air circulation) are partially recreated in the memorial experience. Entry: USD $4/person. Duration: 45–60 minutes with the guide included in the entry price. The memorial’s emotional weight makes it appropriate for older children and adults; it is heavy material that warrants full attention.
Freddie Mercury’s Birthplace and Forodhani Market
Freddie Mercury (born Farrokh Bulsara in Stone Town in 1946, died London 1991) — the Queen frontman born to a Parsi-Indian family in colonial Zanzibar — has a small house museum at his birthplace (Kenyatta Road, 3-minute walk from the Old Fort, entry USD $3) with photographs and Mercury memorabilia. The house is modest in scale but the biographical context (Mercury left Zanzibar at age 7 and never returned, but his birth in the island’s Indian merchant community is a point of great local pride) provides a human connection to the town’s layered cultural heritage. Evening: the Forodhani Gardens night market (adjacent to the Old Fort, opening 18:00 daily) — the best cheap food experience in Stone Town: grilled Zanzibar mix (octopus, squid, king prawns on a stick — the signature Forodhani dish), Zanzibar pizza (a fried flatbread wrap of egg, vegetables, and Zanzibar spices), and sugar cane juice. Budget USD $5–8 for a full Forodhani feast.
