In 1347, Charles IV signed a decree establishing a new city on the right bank of the Vltava. The church was the first church in this area. It was named after King Henry II the Holy and his wife Kunguta of Luxembourg. The complex, which consisted of a church with a bell tower, a priest's residence, a parish school and a cemetery, was built in 1348. His solemn consecration took place in 1351 with the participation of the first Prague bishop Arnoš t of Pardubice. During the Hussite Wars, the church belonged to the Hussites, then came under the control of the Utraquists, and was later returned to the Roman Catholic Church.→
