Church of Our Lady Assumed into Heaven (also known as St. Mary's Church) is a Brick Gothic church famous for its wooden altarpiece carved by Veit Stoss. According to chronicler Jan Długosz the first parish church at the Main Square in Kraków was founded in 1221–22 by the Bishop of Kraków, Iwo Odrowąż. The building was destroyed during the Mongol invasion of Poland. Between 1290–1300 the new early Gothic church was built on the remaining foundations. It was consecrated twenty years later, in 1320.
The church was completely rebuilt under the reign of Casimir III the Great between 1355 and 1365 with substantial contributions from wealthy restaurateur Mikołaj Wierzynek. The presbytery was elongated and tall windows added. The main body of the church was completed in 1395–97 with the new vault constructed by master Nicholas Werhner from Prague. However, the vault over the presbytery collapsed in 1442 due to a possible earthquake, which never happen before nor after in Kraków.
In the first half of the 15th century, the side chapels were added. Most of them were the work of master Franciszek Wiechoń. At the same time the northern tower was raised and designed to serve as the watch tower for the entire city. In 1478 carpenter Maciej Heringh funded a helmet for the tower. A gilded crown was placed on it in 1666, which is still present today. At the end of the 15th century, St Mary's church was enriched with a sculptural masterpiece, an Altarpiece of Veit Stoss (Ołtarz Mariacki Wita Stwosza) of late Gothic design.
In the 18th century, by the decision of vicar Jacek Augustyn Łopacki, the interior was rebuilt in the late Baroque style. The author of this work was Francesco Placidi. All 26 altars, equipment, furniture, benches and paintings were replaced and the walls were decorated with polychrome, the work of Andrzej Radwański.
At the beginning of the 19th century, the city has decided that a cemetery near the Basilica was to be shut down and made into a public square. Today it is known as Plac Mariacki (The Marian Square). In the years 1887–1891, under the direction of Tadeusz Stryjeński the neo-Gothic design was introduced into the Basilica. The temple gained a new design and murals painted and funded by Jan Matejko, who worked with Stanislaw Wyspianski and Józef Mehoffer - the authors of stained glass in the presbytery.
On every hour, a trumpet signal—called the Hejnał mariacki—is played from the top of the taller of St. Mary's two towers. The plaintive tune breaks off in mid-stream, to commemorate the famous 13th century trumpeter, who was shot in the throat while sounding the alarm before the Mongol attack on the city. The noon-time hejnał is heard across Poland and abroad broadcast live by the Polish national Radio 1 Station.
St. Mary's Basilica also served as an architectural model for many of the churches that were built by the Polish diaspora abroad, particularly those like St. Michael's and St. John Cantius in Chicago, designed in the so-called Polish Cathedral style.
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.
