In 1623, Archduchess Isabella granted the order of Brigitte the right to settle in Brussels. In 1637, the Confrérie des Brigittines, originally from Dendermonde, bought a property on the site of the present rue des Brigittines. In 1663, they built a convent with a chapel, designed by the architect Léon Van Heil in the Italian-Flemish Renaissance style. During the bombardment of 1695, which reduced most of Brussels to ashes, the building suffered little damage. However, in 1784, Joseph II put an end to the religious vocation of the building. Disused as a religious monument from 1783 to 1920, the chapel was put up for public sale. The City of Brussels acquired it two years later and, thanks to a successful restoration, saved it from almost two centuries of setbacks and various uses. A contemporary extension to the chapel was inaugurated in 2007.

The cathedral of Saints Archangels Michael and Gabriel is the old church of the Jesuit fathers. The church dates from the 19th century (1874) and was given to the Greek Orthodox worship.

The church of Saints John and Stephen the Minimes, known locally as the "Church of the Minimes", was first built in 1624, but it soon proved too small, so a new church was built from 1700 to 1715. The new church presents an architectural style of transition between Brabantine baroque and early classicism. During the French Revolution, the church was closed in 1796. It was not until the independence of Belgium (1830) that the church finally opened without interruption. Restoration work, directed by Tilman-François Suys and Pierre Victor Jamaer, was carried out at the end of the 19th century. The convent and cloister of the Minimes were demolished in 1920 to make way for the construction of the Athénée Robert Catteau.
