The church dedicated to St. Francis Xavier was built at the Town Hall Square in the Old Town of Kaunas by Jesuits. They opened their first residence in Kaunas in 1642 and established a chapel in the House of Perkūnas in 1643. Later they also founded a first four-form school in the city in 1649. The construction of the church started in 1666, and it was consecrated in 1722.

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.
