Loropeni Ruins

Loropéni was declared a World Heritage Site by UNESCO in 2008. It is one of the few surviving ruins in West Africa. In fact, it's one of the oldest and best preserved. Its size is impressive. The walls are up to 7m high and 1.5 m wide at its base, marking off an area of ​​40m by 50m. The bricks are made of stone, a material that is very unusual here and the bricks explain its good condition. The funny thing is that nobody can agree on the date of construction. Some historians claim it was in 16th century and others in the 18th century. Nobody seems to know what explains this mysterious building in the woods! And no one knows who built it.
