Our Lady of Leliendaal Church was originally owned by the Norbertine St. Michael's Abbey in Antwerp. The architect was Lucas Faydherbe, he came from Mechelen, was the nephew of Lucas Franchoys the Younger and studied with Peter Paul Rubens in Antwerp. In 1662, the foundation stone was laid. Construction was delayed on multiple occasions, because the façade tilted dangerously forward. Therefore, in 1664, the façade was demolished and rebuilt. In 1670, the first Mass was said and in 1674 it was solemnly inaugurated.
In the early 19th century, during the Napoleanic wars, the church was seriously neglected and half of it was turned into a hospice for the poor of the city. The furnishings were sold and holes were made in the gables for people to be able to see out and over the church to help defend it against attack. A wall was placed in the church between the second and third windows for the establishment of an infirmary.
In 1834, it re-opened under the administration of the Jesuits. Through the cooperation of the nearby Minor Seminary and the Civil Hospices, it was restored and equipped with new furniture and the internal walls were removed. In 1900-1901, the Jesuits changed the floor plan and moved the choir to the gallery in the west of the church. Later in the 20th-century, a sacristy was constructed in the south west part of the church. Also, a grotto to Our Lady of Lourdes was built and new furniture was purchased.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
