I visited the biggest Basilica in the world! Basilica of our Lady of Peace (Basilique Notre-Dame de la Paix), Yamoussoukro. It is modelled based on the Basilica of St. Peter in the Vatican but is the tallest and biggest in surface area in the world.
It took three years to build, between 1986 and 1989 and was consecrated by Pope John Paul II.36 companies were involved in building it, while the architecture and design was done by a Lebanese architect called Pierre Fakhoury.
The structure might not look so impressive from outside...
