Igreja do Santíssimo Sacramento e de Santa Teresinha de Lisieux, Catholic church in Bom Fim district, Porto Alegre, Brazil

Igreja do Santíssimo Sacramento e de Santa Teresinha de Lisieux is a neo-Gothic church begun in 1924, with a single octagonal tower projecting forward from the facade. Each tower level sits on a wider drum ringed by an open balustrade with pinnacles, pierced by double pointed openings crowned with quatrefoils. The steep spire, clad in a fish-scale texture, is topped by a statue of the patron saint by Alfred Adloff.

The foundation stone was laid on 6 January 1924, and the church was solemnly inaugurated on 27 September 1931. It was one of the first temples built in honour of Saint Therese of Lisieux, canonised in 1925. In 1970 it was elevated to parish status, receiving the additional title of the Blessed Sacrament in memory of the Eucharistic Congress held in Brasília.

The church is dedicated to Saint Therese of Lisieux, canonised in 1925, and was one of the first temples built in her honour. In 1970 it became a parish and received the additional title of Santíssimo Sacramento, recalling the Eucharistic Congress held in Brasília. The parish is served by the Discalced Carmelites.

The church stands in the Bom Fim district, with its single tower projecting forward over two doors set at 45 degrees to the street; visitors enter through a vestibule inside the tower before reaching the nave. The parish is served by the Discalced Carmelites.

The stained glass windows come from two different sources: most were made by Porto Alegre's Casa Genta, while a large piece on the facade was created by Madrid's Sociedad Maumejean Hermanos. This combination shows how local and international craftsmanship shaped the building.
