I would call this a meager harvest. I did not find a house with an architects signature displaying the year 1866. Perhaps readers could help finding one.
What I found is a memorial in a house in “Place des Barricades / Barricadenplein” where the French writer Victor Hugo lived from 1866 till 1871 (see my post on 1971).
I also found a façade in which the year 1866 is displayed in roman numbers.
This year was rich in discoveries.
The reader will notice that I found some interesting items to capture with my camera.
One picture is about the memorial of Leon Delcroix, a Belgian composer who lived in Brussels. I also took a picture of a statue of the Virgin Mary with the year 1938 displayed in the pedestal. This statue is located at the entrance of a school nearby the Sainte Suzanne chuch (see my post on 1932).
The year 1936 seems an easy one when it comes to finding buildings architects signatures displaying that year.
