A Belgian painter-collector donated his art-collection to Sint-Gillis.

Thanks yleor for the two clues but these were really not needed as the reverse image search itself revealed the full story. The news reports about this painting mention that it was found in the

town hall of Saint (Sint) Gillis.

The building is easy to locate but unfortunately I cannot get matching image of the glass building posted by you, Walter_V_R and krenek . I have spent several hours poring over the area and also going around the building but no success. Some web sites even mention the urban office in which it was found but Google and Google Maps have not been of any help in locating that particular office.

I will wait for 3rd clue now. 

Silly of me I missed the most important clue - the Title of the post, hence couldn't understand the second clue! 

Thanks to a little bird  I got on the right track. Even then it took some time to find it. Good puzzle yleor.

I definitely needed help on this one.  

Despite any help well done Utapao!

Léopold Speeckaert donated after his death in 1915 the painting of Jordaens to the municipality of Sint-Gillis, near Brussels. It turned out to be an original painting. His house became a museum, but exists no longer, it is a modern building these days.

i found some different information:

according to this website
monument.heritage.brussels/fr/Saint-Gilles/Avenue_Henri_Jaspar/113/4713 = SV link
the museum was not at "your" place
the correct new building is

it reads "Il remplace trois maisons néoclassiques, dont le Musée Speeckaert au no 114" = "Het vervangt drie neoklassieke huizen, waaronder het Speeckaertmuseum op nr. 114" (google translation)

i wrote to you about that but i'm not sure you read my message!?

Hello krenek,

I’m sorry about the misunderstandings. In Wikipedia the name is probably misspelled: Léopold Speekaert. According to that lemma, in Dutch, the artist lived for a long time at Gulden Vlieslaan 114. My apologies!
