Church of Our Lady of the Annunciation

The Church of the Holy Trinity is a 19th-century religious building, whose 17th-century baroque facade is that of the former church of the Augustinians, demolished in 1893 to allow the creation of the Place de Brouckère. In the 19th century, as part of the development of the Avenue Louise, Léopold I wanted to develop and urbanise the Dix Bosch district in Ixelles. He had a temporary chapel built there (between 1847 and 1857) on land donated by the banker Georges Brugmann, who also contributed to its financing. The new church was built between 1893 and 1907, the architects being J. J. Van Ysendijck and Jacques Franquart.

St Andrew's Church, the only Scottish church in Belgium, is characterised by its English neo-Gothic style. Built in 1925, the façade is signed "J. Waddell and T. Young / Glasgow / Walthère Michel / Architects". The church was built in memory of the Presbyterian soldiers who died in the First World War.

St. Mary Magdalene Church is an Armenian Orthodox religious building built from 1986 to 1990 in a postmodern style. In the early 1980s, the non-profit organization Foundation for the Armenian Church in Belgium started to raise funds for the construction of a church. His project was designed by the architect Haïk Mardikian and the engineer Jacques Kupélian who were inspired by the shape of the Holy Cross Church of Aghtamar.
