The church is located between partitions, with its façade on the chamfered corner, between Carrer de Balmes and València, set back from the houses in order to make it stand out and ensure good visibility of the building. It differs from the parish buildings on the sides, which are lower and slightly further back from the line of the façades. The use of materials also contrasts with a certain monumentalisation: the side buildings with exposed pressed brickwork in a combination of red and white and the grey Montjuïc stone. The façade of the church also has a pediment with a gable roof that hides the open roof terrace.
The ground plan of the church begins at the chamfered corner and crosses the site diagonally, leaving space on either side for the parish buildings. In order to ensure good lighting in the church, roof terraces were designed on the upper part to open large parabolic arched windows in the dome and light courtyards with skylights that would give zenithal light to the interior windows.
The interior of the church is richly decorated, largely by the architect himself: from the base of the marble slabs, coffered ceilings, polychrome plaster mouldings, stucco, decorated ceramic tile floors, leaded glass windows and lamps to the liturgical furnishings.
The frescoes and sgraffito were painted by Ferdinandus Serra, and the Venetian mosaics by Lluís Bru. The stained glass windows are the work of Joan Bonet, with scenes of the Virgin of the Angels and the saints who were most closely associated with the city of Barcelona. Along these lines, there is a carving of the Virgin of the Angels by Martí Cabrer.
The architect designed the church and the parish annexes during the Republican period, commissioned by the rector Joaquim Delgé at the end of 1932, but construction did not begin until after the Spanish Civil War, from 1942 onwards. The solutions adopted by the architect place the church halfway between the new religious architecture that was prevailing in Europe and the Catalan Noucentista past, opening up a line of continuity with tradition by providing modern solutions.
The parish complex was promoted by the Junta de Obra de la Parroquia de Nuestra Señora de los Ángeles following a programme that included the construction of two annexed buildings for the parish school and the rectory. Work began in 1942, following the 1934 project. The inauguration of the church took place in 1950, when part of the interior decoration was still missing. In 1952 the chandeliers were installed, and on the 12th of October 1955 the church was consecrated and on the 25th December 1956, the altar of the Blessed Sacrament.
