Kilwa Kisiwani Ruins

The island across the channel

Kilwa Kisiwani is the larger of the two islands that together form the World Heritage property inscribed in 1981 as the Ruins of Kilwa Kisiwani and the Ruins of Songo Mnara. The site’s integrated management plan for 2025 to 2035 places it about two kilometres south of Kilwa Masoko harbour and gives its area as around 32 square kilometres, with most of the monuments in the north-west, spread east to west of the village. It is reached by boat from Kilwa Masoko, which is where you sleep, arrange access and hire the boat.

The plan dates the earliest houses on the site to the ninth century AD and records that mobile groups had used the island landscape for two millennia before that. The city was at its height in the thirteenth and fourteenth centuries, and when Ibn Battuta stopped here in the early 1330s he described Kilwa as one of the most beautiful cities in the world. The ruins were declared National Monuments in 1937, under Government Notice No. 186 of that year, and have been protected under the Antiquities Act of 1964 since.

What is on the island

The management plan itemises the site far more fully than the World Heritage listing does. The mosques are the Great Mosque; the fifteenth-century Small Domed Mosque, whose domes have imported Persian fritware bowls set into the plaster; Malindi Mosque, fifteenth century and renovated in the eighteenth, with an ablution area, a well and water tanks in its courtyard; the Jangwani mosque and house, mostly rubble and only partly excavated; and the Makutani mosque, with pillars, a wall and a standing mihrab.

The palaces and defensive structures are Husuni Kubwa, Husuni Ndogo, the Makutani Palace and the Gereza Fort, together with the Great House — a fifteenth-century structure south of the Great Mosque, separated from it by what the plan calls the last surviving example of the streets the Portuguese recorded at Kilwa.

There are also four burial grounds: the Cemetery of the Forty Sheikhs, the Kilwa Sultan’s Mausoleum, the Malindi cemetery, and the Sake cemetery, whose tombs may go back to the eleventh century.

One thing to know before you are offered it

The Cemetery of the Forty Sheikhs is not open to visitors. The management plan describes it as a burial area holding the tombs of Kilwa’s sultans, mainly of the eighteenth century, treated as sacred by the community and therefore off-limits to tourists, and it lists the absence of human entry as a monitoring indicator for the site. If a guide offers it, that is the answer.

What condition it is in

The property was on the List of World Heritage in Danger from 2004 until 17 June 2014. The 2025 plan reports the Gereza Fort, the Makutani Palace, Husuni Kubwa, Malindi Mosque, the Cemetery Mosque and the Great Well in a good state of conservation, and puts about 90 per cent of the island’s monuments in the well-preserved category, with ruined walls that still need strengthening. Three have not been restored: Husuni Ndogo, the Jangwani house and mosque, and the Great House. The live threats it names are wave action along the northern shoreline, plant growth after each rainy season, goats and cattle entering the ruins, sand and coral mining, and encroachment by new building.

Getting there, and how busy it is

Access is by boat from Kilwa Masoko to a rehabilitated jetty at the northern tip of the island. The crossing is tide- and weather-dependent, which is why a Kilwa visit is planned around the water rather than the clock. Take water, sun cover and shoes for coral rubble and scrub.

Expect to have it largely to yourself. The plan records 6,369 visitors to both islands in 2022/23, of whom 1,198 were international — about 23,400 people in total across the five years to 2022/23. This is a World Heritage property receiving roughly a thousand foreign visitors a year. See archaeological tours for how these sites are read, and Swahili cultural tours for the wider coastal story.
