Basilica of Our Lady of Peace of Yamoussoukro

The Basilica of Our Lady of Peace is a Catholic minor basilica dedicated to Our Lady of Peace in Yamoussoukro, the administrative capital of la Côte d'Ivoire. Guinness World Records lists it as the largest church in the world, having surpassed the previous record holder, Saint Peter's Basilica, upon completion. It has an area of 30,000 square metres and is 158 metres tall. However, it also includes a rectory and a villa, which are not strictly part of the church. It can accommodate 18,000 worshippers, compared to 60,000 for St. Peter's. Ordinary liturgies conducted at the basilica are usually attended by only a few hundred people. The basilica is administered by Polish Pallottines at a cost of US$1.5 million annually.

The basilica was constructed between 1985 and 1989 with different cost estimates given by various groups. Some stated that it cost US$175 million, US$300 million, or as high as US$600 million.
