The aqueduct was finished in 1615, and an ornamental gateway known as the Wignacourt Arch (or Fleur-de-Lys Gate) was built where it crossed the road.

By 1941 the British had built Fleur de Lys Battery in the area armed with anti-aircraft artillery.

Other chapels were later built in Fleur-de-Lys, including those in the Sisters of the Sacred Heart Convent and one in St Monica School.
