Leonard Sharp & Bwama Island: Lake Bunyonyi

In 1921, a Scottish physician named Leonard Sharp paddled a dugout canoe across Lake Bunyonyi and chose an island. He was not looking for a view. He was looking for a place to contain a disease that Uganda's colonial administration was struggling to control — and isolation, in the medical thinking of the time, was the best tool available. What he built on Bwama Island over the following decades became one of the most significant medical institutions in East Africa, and one of the strangest footnotes in the history of a lake that today markets itself primarily for its scenery.

Who Was Leonard Sharp?

Leonard Sharp was a Scottish missionary doctor affiliated with the Church Missionary Society (CMS). He arrived in Uganda in the early twentieth century during a period when colonial medical infrastructure in the region was rudimentary at best. Leprosy — a chronic bacterial infection that causes progressive nerve damage and disfigurement — was spreading through communities in southwest Uganda without any formal treatment or management system.

Sharp identified Lake Bunyonyi, then a relatively isolated body of water in what is now Kabale District, as a potential site for a dedicated hospital. Bwama Island, one of the lake's 29 islands concentrated in its central section, offered the dual advantage of physical separation from the mainland and sufficient flat land for a facility (source: Reiseführer Uganda 2020 — Teil 10).

Bwama Island: From Hospital to School

Sharp founded the Bwama Island leprosy hospital in 1921, according to Reiseführer Uganda 2020 — Teil 10. The facility grew steadily over the following decades as patients were referred — and in many cases transported — from communities across the southwest.

At the epidemic's peak, which the same source places in the 1980s, the hospital was caring for approximately 5,000 patients. That figure is striking for an island-based facility, and reflects both the scale of the leprosy burden in the region and the degree to which Bwama had become a permanent community rather than a transit facility. Patients lived there — some for decades. Families formed. A settlement grew up around the medical compound.

The transformation came in the 1980s, when the introduction of multi-drug therapy made leprosy treatable on an outpatient basis. Patients no longer needed to be isolated; they could be treated in their home communities and recover fully. The population of Bwama Island declined as the medical rationale for residency disappeared. The hospital eventually closed as a leprosy facility.

Today, Bwama Island is a school. A boarding institution now occupies much of the land where patients once lived and were treated. The shift from medical isolation colony to education centre carries a certain quiet symbolism — a place defined by exclusion becoming a place defined by inclusion and opportunity.

Sharp Island: Where the Family Lived

Immediately adjacent to Bwama is Njuyeera Island, which locals and guidebooks call Sharp Island — named directly for Leonard Sharp, whose family made the island their home during his years of medical work at Bwama. The main house in which Sharp's family lived still stands. It is now the centrepiece of the Sharp Island Gorilla Lodge, which operates from the island today (source: Reiseführer Uganda 2020 — Teil 10).

The lodge's name combines both the historical and the contemporary: Sharp's legacy as a formal attribution, and gorilla trekking as the present economic context that brings visitors to this corner of Uganda. It is an unusual combination — a Victorian missionary dwelling repurposed as a gateway lodge for wildlife tourism — but on Lake Bunyonyi, that kind of layered history is more the rule than the exception.

The Lake Itself: Geography and Scale

Lake Bunyonyi stretches approximately 25 kilometres in length and 7 kilometres in width, according to Reiseführer Uganda 2020 — Teil 10. It sits in a valley in southwest Uganda at roughly 1,960 metres above sea level — high enough that the water is cool and free of the bilharzia parasites that make swimming in many Ugandan lakes inadvisable. The lake is genuinely swimmable, which distinguishes it from most freshwater bodies in the region.

The 29 islands vary considerably in size, character, and history. Some are uninhabited. Some hold small lodges. A few, like Bwama and Njuyeera, carry specific historical weight. Akampene — Punishment Island — carries the most uncomfortable history of all: unmarried pregnant women from the Bakiga community were historically left there to die, a punishment rooted in the economics of bride price that continued until the colonial period. It is visited today by canoe as a historical landmark, its story told by guides with the kind of directness the subject requires.

Community Life Along the Shore: A Present-Day Perspective

Visiting southwest Uganda in October 2024, we spent time in and around Buhoma in the Kanungu District — a region that sits within the same cultural and geographic sphere as Lake Bunyonyi. The communities along the lake's shores and in the surrounding valleys carry traditions that predate the missionary hospitals and the colonial administration that brought doctors like Leonard Sharp here.

In Buhoma, we visited an orphanage run by Nicholas and Media — a small, structured community of children who have found stability and care in difficult circumstances. On the last day of our stay, we bought soda and fresh watermelon and held a simple farewell gathering with the children and staff. It was an unceremonious occasion: drinks, sliced fruit, conversation. But those simple gestures of hospitality and human connection are what Leonard Sharp would have encountered daily on Bwama Island — and what made the work there something more than a medical project.

The children performed a traditional dance during one of our visits — a sequence that, according to the staff, represents episodes from Uganda's history. It is a physically demanding performance; the rhythm is relentless, and the children danced for a sustained period in the midday heat with minimal water breaks. Watching it, you are aware of something being carried forward: not just movement, but memory.

On another morning, we bought food at a small shop near the orphanage for families in the community. The shop had no windows — just a single entrance door — and its shelves held everything a household might need: dried beans, soap, bread, sweets, basic goods. This is the infrastructure of daily life in rural southwest Uganda, largely unchanged in its essentials since the time when patients on Bwama Island depended on similar supply chains across the water.

What Remains of Leonard Sharp's Work

Sharp's legacy on Lake Bunyonyi is architectural, institutional, and toponymic. His family's house on Sharp Island survives as a lodge building. The school on Bwama Island occupies the land he chose for the hospital. His name is still used by locals and mapmakers for the island where he lived.

What the history does not supply — and what is worth acknowledging honestly — is a complete picture of what the leprosy colony meant for the people confined to it. Isolation as a medical policy is now understood to be unnecessary and often harmful: leprosy's transmission risk is low, and separating patients from their families had significant psychological and social costs that the medical benefits, such as they were, did not offset. Sharp appears to have operated within the medical consensus of his time and to have provided genuine care within an imperfect framework. The distinction matters.

The patients who lived on Bwama Island for decades, the families that formed there, and the community that evolved around the hospital — these are the stories that are harder to recover. The island's school is one form of continuity. The oral histories held by communities around the lake are another.

Visiting Bwama and Sharp Island Today

Both islands are accessible from the mainland shore by dugout canoe or motorboat. Canoe hire can be arranged through accommodations along the lake or independently at the water's edge. Bwama Island's school is an active institution; visitors should approach respectfully and confirm whether the site is open before landing. Sharp Island's lodge operates as a guesthouse and can be visited or booked for overnight stays.

Frequently Asked Questions

Who was Leonard Sharp and what did he build at Lake Bunyonyi?

Leonard Sharp was a Scottish missionary doctor affiliated with the Church Missionary Society. In 1921 he founded a leprosy hospital on Bwama Island in Lake Bunyonyi, southwest Uganda. At its peak the facility cared for approximately 5,000 patients. The introduction of effective multi-drug therapy in the 1980s made isolation-based treatment unnecessary, and the hospital eventually closed. The island is now home to a school.

Can you visit Bwama Island today?

Yes. Bwama Island is accessible by dugout canoe or motorboat from the lake's mainland shore. The island now hosts an active boarding school; visitors should approach respectfully and check whether the site is open before landing. Sharp Island (Njuyeera), immediately adjacent, operates as Sharp Island Gorilla Lodge and can be visited or booked for accommodation.

What is Sharp Island and why is it called that?

Sharp Island — officially Njuyeera Island — was the home of Leonard Sharp's family during his years of medical work on Bwama. The house where the family lived still stands and is now the main building of Sharp Island Gorilla Lodge. The informal name has persisted through local use and guidebooks despite the island's official name.

What is Punishment Island (Akampene) at Lake Bunyonyi?

Akampene, known as Punishment Island, carries one of Lake Bunyonyi's most uncomfortable histories. Bakiga women who became pregnant outside marriage were historically abandoned on the island — a punishment rooted in the social economics of bride price that continued into the colonial period. Today it is visited by canoe as a historical site; guides discuss its history directly.

Is Lake Bunyonyi safe to swim in?

Yes — Lake Bunyonyi is one of the few Ugandan lakes where swimming is safe. Its altitude (approximately 1,960 metres) and water chemistry mean it is free of the bilharzia (schistosomiasis) parasites that make swimming inadvisable in most other Ugandan lakes.

How does Bwama Island fit into the history of leprosy in Uganda?

Bwama Island was established under the prevailing medical belief that physical isolation of leprosy patients was necessary and beneficial. This approach is now understood to have been medically unnecessary — leprosy's transmission risk is low — and socially harmful, separating patients from families for years or decades. Sharp operated within his era's medical consensus; the standard critique of isolation-based colonial medicine applies here as it does elsewhere.
