Moroni is one of Africa's smallest and least-visited capitals, and that is exactly why it is one of the most authentic in the Indian Ocean. Stretched along the west coast of Grande Comore, at the foot of the huge Karthala volcano, it is a city of white houses, narrow alleys, coral-stone mosques and a harbour where dhows still dock: the lateen-sailed Arab boats that for centuries linked these islands with Zanzibar, Arabia and the Swahili coast.
The heart of the city is the Vieille Ville or Medina, a maze of shady alleys with carved wooden doors, inner courtyards and little squares, dominated by the 15th-century Old Friday Mosque (Ancienne Mosquée du Vendredi or Badjanani), whose white and green minaret is reflected in the sea. In 2026 this medina, together with those of Iconi, Mutsamudu and others, was declared a UNESCO World Heritage Site. All around, Comorian life bustles on: the call to prayer, the markets selling spices, ylang-ylang and vanilla, and the comings and goings of the dhows.
This guide explores Moroni with a practical eye: what to see in the city and its medina, how to visit the mosques and the waterfront, where to eat fresh fish and how to use the capital as a base for the big excursions on Grande Comore, starting with the Karthala volcano. A remote, peaceful and deeply Islamic destination, ideal if you're looking for an off-the-beaten-track corner of the Indian Ocean full of character.
Moroni has existed since at least the 10th century as a port for Swahili and Arab traders on the Indian Ocean dhow route. It was the capital of one of Grande Comore's sultanates, and its Old Friday Mosque was built in the 15th century. Under French rule from the late 19th century, in 1958 it replaced Dzaoudzi (Mayotte) as the administrative capital, and since independence in 1975 it has been the capital of the Union of the Comoros. Its history of sultanates, Indian Ocean trade and political turmoil is told on our history page.

Origins, formation and what the sources say.
The history of Moroni, and of the whole Comoros archipelago, was written by the sea. The islands lie in the Mozambique Channel, halfway between the coast of East Africa, Madagascar and the routes to Arabia and India. From very early on they were a natural stopover in the great Indian Ocean trade, driven by the monsoon winds and by dhows, the Arab sailing ships with lateen sails. The first settlers probably arrived around the 6th or 7th century, in waves of Bantu and Austronesian peoples (the Austronesians came from Southeast Asia via Madagascar), followed later by Arabs and Persians.
Islam came with trade. Between the 9th and 15th centuries, Swahili, Arab and Shirazi merchants and settlers made their homes on the islands. According to tradition, the Shirazi were Persians from Shiraz. These newcomers brought the islands into the Swahili civilisation that flourished along the whole East African coast, from Mogadishu to Kilwa and Zanzibar. The result was a string of coastal city-states run by Muslim traders, with coral-stone houses, mosques and an elite that grew rich on the trade in slaves, gold, ivory, spices, ambergris and tortoiseshell.
Moroni, on the west coast of Ngazidja (Grande Comore), was one of those port towns. Its name is usually translated as 'in the heart of the fire', because it sits at the foot of the Karthala volcano. Like the other settlements on the islands, it lived off maritime trade and the coming and going of the dhows that linked the Comoros with Zanzibar, Kilwa, the Swahili coast and the Arab world. That network of exchange gave the islands their mixed character, African and Muslim at the same time.
From the Middle Ages onwards, each island in the archipelago split into small rival sultanates. Grande Comore alone had as many as ten at once, ruled by local dynasties that combined African lineage with claims to prestigious Arab or Shirazi origins. These sultans competed for control of trade, forming alliances and going to war, and in their capitals they built stone mosques and palaces that still stand today.
This was the setting for Moroni's jewel, the Old Friday Mosque, known as the Ancienne Mosquée du Vendredi or Badjanani. Tradition says it was completed on a Friday in 1427, which makes it one of the oldest mosques in the archipelago and a symbol of the city. It is built of coral stone and volcanic rock and mixes Arab and Swahili influences. Its distinctive white-and-green minaret was added much later, in 1921, and today it towers over the harbour front, reflected in the sea.
The Vieille Ville, or Medina of Moroni, grew up around the mosque. It is a maze of narrow alleys, carved wooden doors, inner courtyards and small neighbourhood mosques, typical of the Swahili towns of the Indian Ocean. Almost six centuries later, in 2026, this old town was recognised as a World Heritage Site, together with the medinas of Iconi, Mutsamudu, Domoni and others.
In the 19th century the Comoros were drawn into the French colonial empire. France established a protectorate over Mayotte in 1841 and extended its rule to the other islands between 1886 and 1892, until the whole archipelago became a colony. For decades the islands were run from Mayotte, with the colonial capital at Dzaoudzi on the islet of Pamandzi. Moroni was the most important town on Grande Comore, but it played only a minor role in the administration.
That changed in the mid-20th century. In 1958 the capital of the territory moved from Dzaoudzi to Moroni, which became the political and administrative centre of the Comoros. The city grew and modernised, and it gathered the institutions, the port and most of the trade. Under French rule the plantation economy that still defines the country also took shape: vanilla, cloves and, above all, ylang-ylang. Ylang-ylang's fragrant essence made the islands a key supplier to the world perfume industry and earned them the nickname 'the perfume islands'.
On 6 July 1975, after a referendum, the Comoros declared independence from France. Mayotte, however, voted to remain French and is still under French administration today. The Comoros have never accepted this and still claim the island. Moroni became the capital of the new independent state, the Union of the Comoros.
Independence opened one of the most turbulent chapters in recent African history. Barely a month after declaring it, President Ahmed Abdallah was overthrown in a coup, the first of a long series. Between 1975 and 2008 the Comoros went through an estimated twenty coups and coup attempts, roughly one every year and a half. This gave the country the sad reputation of being one of the most unstable nations in the world.
One of the most sinister figures of the period was the French mercenary Bob Denard, who meddled in Comorian politics again and again for almost two decades. He took part in several coups. One of them, in 1978, overthrew and led to the death of Ali Soilih, a Maoist-inspired revolutionary who had attempted a radical transformation of society. As head of the presidential guard, Denard effectively controlled the country for years. His shadow over Moroni only lifted when France intervened militarily in 1995 to remove him.
Political instability was compounded by tensions between the islands. In 1997, Anjouan and Mohéli tried to break away from the Union. The crisis was only resolved in the early 2000s, with a new Constitution that gave each island broad autonomy and set up a rotating presidency. Through it all, Moroni remained the centre of national life and the seat of the government, the parliament and the institutions of a small, poor but resilient country.
Today's Moroni is a small, quiet capital of around 60,000 people. It keeps the feel of a Swahili port while it grows, with new neighbourhoods, a large modern mosque funded with help from the Gulf states and a modest service sector. The country's economy still depends on export crops (vanilla, cloves, ylang-ylang) and on fishing. Above all, it depends on money sent home by the huge Comorian diaspora in France, which is far larger than the population of some of the islands.
Tourism is still in its infancy. The Comoros receive very few visitors a year, which makes Moroni a genuine destination, free of crowds. Travellers find hospitality, prices paid in cash and a daily life shaped by Islam, the sea and the volcano. The city offers few luxury services, but in return it has an authenticity that is hard to find in the more developed destinations of the Indian Ocean.
The big recent milestone came on 25 July 2026. Meeting in Busan (South Korea), the 48th session of the UNESCO World Heritage Committee inscribed the 'Historic Sultanates of the Comoros' as a World Heritage Site. The listing covers six centuries-old medinas, four on Grande Comore, including Moroni's, and two on Anjouan. They are the country's first sites on the list. The Old Friday Mosque, with its green minaret above the dhow harbour, became the image of this recognition. It promises to boost the preservation of these fragile treasures and, perhaps, help tourism take off in the Comorian capital.
