Basilica of the Visitation was built between 1715 and 1723. The basilica was given the status of a basilica minor by Pope Pius XI in 1936. The present basilica is located on a hill, where in the twelfth-century, stood a wooden figure of Mary, the Mother of God. According to a chronicle from 1218, the blind Jan from Raszewo regained his sight there. After the event, many pilgrims began visiting the area. Shortly afterwards, an altar, together with candlesticks and a baptismal font, was placed by the statue under the tree. In 1263, a wooden church was built on the hill.
In 1512, Ludwik von Panwitz raised a greater church, constructed out of brick. However, the church was destroyed during the Thirty Years' War. Between 1695 and 1711, a new church was built, but quickly began to crumble and was deconstructed in 1714. Between 1715 and 1723, another church was built by Count Franciszek Antony von Goetzen, which stands to the present day.
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.
