The Maison Royale is the compound of the Togoville chiefs, who still wield ceremonial authority over the town and its outlying villages. The building itself is a modest single-storey house with a tin roof and a verandah, but its position in the country's history is outsized: this is where the German treaty of 1884 was signed, the foundation document of the Togolese protectorate and the source of the country's name.
A visit usually involves a short tour from a family member or appointed guide, an explanation of the treaty and the lineage of the chiefs, and the opportunity to meet the current king. A small donation is expected. Photographs are usually fine inside, but ask first.
