The Church of Our Lady of Fatima (locally known as Igrejinha - little church) was the first brick-and-mortar church built in Brasília, built by Brazil then First Lady. It was inaugurated with a catholic mass and then a wedding, back in June, 28th 1958. Architect Oscar Niemeyer designed a church with a slab in form of an isosceles triangle, supported by an u-shaped wall, which. Its shape resembles a nun hat, and the use of reinforced concrete in its building allows for unlikely curved shapes, in which the architect plays with the materials. The outer walls decorated by iconic tiles designed by Athos Bulcão, another important name in the city's history. This church was built in 100 days, and it's located in a residential area, with lots of magnificent trees and near to a thriving commercial area. Well worth the visit, which won't take you more than 5 minutes.
