The Palais Sékhoutoureya — known formally as the Palais des Nations — is the official residence and working office of the Guinean president, on the western waterfront of the old Kaloum peninsula. It was built under President Sékou Touré in the 1970s with North Korean assistance, and the long, low concrete facade with its repeating arches has the brutalist-meets-tropical-modernist look common to West African state architecture of the era.
You cannot enter the grounds and you cannot photograph the front gate — soldiers will stop you — but you can walk the seafront road that runs along the western perimeter and get a sense of the scale. The view back from the corniche, with the palace, palm trees, and Atlantic surf, is one of the best in the city.
