World War I is over. In 1919 begins the so called “inter-bellum”, i.e. the period between the two World Wars. As for 1918 I have been unable to take a picture of a house built in 1919. I nevertheless managed to take some pictures of memorials displaying the year 1919.
The one mentioning the name of Joseph Leo Cardijn, a Belgian priest and cardinal and the founder of the Young Christian Workers, can be found in the façade of house (the rectory?), close to the cemetery of Laeken and the Church of Our Lady of Laeken.
