Her name is connected to several places: Moorsel (where she lived), Brussels (where a chapter in her honour was founded in 1047) and Eibingen (where the relic of her skull is conserved).

When Gertrude died, Gudula moved back to her home at Moorsel, spending her time in good works and religious devotion.

She was profuse in her alms for the poor,[4] and frequently visited the church of Moorsel, situated about two miles from her parents' house.

[7] On 6 June 1579, the collegiate church was pillaged and wrecked by Protestant Geuzen ("Beggars"), and Saint Gudula's relics were disinterred and scattered.

She is depicted on a seal of the Church of St. Gudula of 1446 holding in her right hand a candle, and in her left a lamp, which a demon tries to extinguish.

[5][6] The flower called tremella deliquescens, which bears fruit in the beginning of January, is known as Sinte Goedele's lampken (St. Gudula's lantern).
