Hello steemians hope you are having a good day, for today #celestialchallenge initiated by mentor @sirknight ( I am a great fan of your work sir) .
In today topic titled Structure, I would be bring to you the oldest storey building in Nigeria built with indigenous technology even before the coming of the Europeans.
This building is located at Gobarau Minaret and it was built in about 1348-1398 before Nigeria had a contact with the Europeans.
the building was first used in calling for prayers and later for watching over the city against external attacks. And the building is still in existence up till now.
