In 1900, 1920 and 1927, parts of the original municipality were already annexed to Ghent.

[1] On 1 January 1977, the municipality of Oostakker was merged into Ghent.

The miraculous shrine of the Blessed Virgin is a place of pilgrimage from Belgium, the Netherlands and Northern France.

[3] It was first opened to the local peasants on Sundays, but comparatively quickly it became very popular with a large Gothic church starting to be built in 1877.
