This unfinished five-story palace near Touba, Senegal, was built in the early 1980s by businessman El Hadji Ndiouga Kébé as both his private residence and a tribute to Sufi saint Cheikh Ahmadou Bamba. Inspired by Mali’s Great Mosque of Djenné, the structure remains untouched since Kébé’s death, with locals attributing a mythical power to its ornate concrete skeleton.

The La Beach Towers on Accra’s coastline, once envisioned as a luxury residential development, has stood incomplete since 2016 following the murder of co-owner and Ghanaian Parliament member J. B. Danquah-Adu. Known as Accra’s "Empire State Building," the 17-story structure is now suffering from corrosion due to salt air. Locals are debating whether to demolish the building or repurpose it into a factory or warehouse to create jobs for nearby communities.

This 18-story building in Lagos, intended for the Nigeria Social Insurance Trust Fund, has remained unfinished for over 30 years. Originally constructed during Ibrahim Babangida's 1980s regime to alleviate congestion, the project was abandoned after the government moved to Abuja in 1991. Valued at 50 billion Naira (approximately 2.94 billion euros), the structure is now repurposed by locals and is known as Ile Nla (“massive house”).
