Ruínas da Igreja Nossa Senhora da Conceição, Colonial church ruins in Guarapari, Brazil.

Ruínas da Igreja Nossa Senhora da Conceição are the unfinished shell of a church begun in 1677 in central Guarapari. Its walls were laid with stacked stones bound by mortar of clay, sand, crushed shells and whale oil. A fire stopped construction, leaving part of the frontis (facade) and the campanário (bell tower), rebuilt in 1817.

Construction began in 1677 under Francisco Gil de Araújo, donatário of the captaincy, to replace an earlier chapel dedicated to the same saint. The building was never finished after a fire, and its remains later served as a cemetery, a jail and a vegetable garden for public school pupils. The façade and bell tower were rebuilt in 1817, and the ruins were listed by the Espírito Santo State Council of Culture in 1989.

Since 2015 the Sinestesia collective and other Guarapari groups have held the Sarau Ruínas in front of the ruins, an independent poetry and performance gathering that reached five editions by 2021, one of them online during the Covid-19 pandemic. Organisers state its aims as making the monument visible, strengthening local memory and occupying the public space.

The site sits on elevated ground with views toward the Atlantic Ocean and nearby beaches. It is best visited during daylight hours and visitors should move carefully through the protected ruins.

The ruins stand on a rise above the beach with ocean views that often surprise visitors. This position makes it a rare example of a colonial church with a seaward outlook.
