Chapel of Our Lady of Help, Roman Catholic chapel in Cachoeira, Brazil

The Chapel of Our Lady of Help is a stone-and-lime church of deliberately simple proportions, made up of a nave, chancel, sacristy, porch and bell tower. A gable roof covers the nave while a tiled brick cupola tops the chancel. Its wooden portal opens from a sloping-roofed porch enclosed by a wooden railing, once a closed narthex; two choir windows and an oculus sit above it, and a small pyramidal bell tower with a tin roof stands alongside.

Álvaro Rodrigues Celestino Adorno built a chapel on a hill dedicated to Our Lady of the Rosary between 1595 and 1606. His great-grandson João Rodrigues Adorno rebuilt it in stone and lime between 1673 and 1687. Father Miguel de Araújo Adorno celebrated the first Mass in October 1686, apparently before completion. The church was later associated with the Brotherhood of Our Lady of Help, whose musicians visited in 1872.

The chapel is home to the Brotherhood of Our Lady of Help, whose musicians visited and joined the church in 1872; the sources give no earlier founding date for the brotherhood. The chapel also draws many pilgrims devoted to Our Lady of Help. The small hall attached to the right of the building dates to the 19th century.

The chapel stands on a hilltop reached by three steeply sloped streets, with its front facing west toward the Paraguaçu River. The bell tower and choir are reached by an external stairway, a feature shared with other early Brazilian churches. A small hall added on the right side dates to the 19th century.

The interior features religious statues of Saint Francis, Saint Benedict, Saint Lucy, Saint Cajetan, and Saint Peter alongside a stone-supported pulpit. This collection of sacred images reflects layers of devotion from different groups of believers who have worshiped here over the centuries.
