The name Bijgaarden is derived from the Germanic word for enclosure. The appellation "Great" (Groot) was attached to distinguish it from the smaller Klein-Bijgaarden nearby, now in the municipality of Sint-Pieters-Leeuw.
History
The earliest record of Groot-Bijgaarden is in the 12th century, when it appears as Bigardis. This derives from the house of Bijgaarden. They made various contributions to the abbeys of Affligem and Groot-Bijgaarden. As a result of different marriages, the village came into the hands of the Veele Family, an important family from Brussels.
After many donations, Groot-Bijgaarden was publicly sold to the counts of Königsegg-Erps in the second half of the 14th century.
