St John's Kirk is architecturally and historically one of the most significant buildings in Perth. The settlement of the original church dates back to the mid-12th century. During the middle of the 12th century, the church was allowed to fall into disrepair, when most of the revenues were used by David I to fund Dunfermline Abbey. The majority of the present church was constructed between 1440 and 1500.
Though much altered, its tower and lead-clad spire continue to dominate the Perth skyline. The Church has lost its medieval south porch and sacristy, and the north transept was shortened during the course of the 19th century during street-widening. A rare treasure, a unique survival in Scotland, is a 15th-century brass candelabrum, imported from the Low Countries. The survival of this object is all the more remarkable as it includes a statuette of the Virgin Mary. St John's Kirk also had the finest collection of post-Reformation church plate in Scotland (now housed permanently in Perth Museum and Art Gallery). Equally remarkably, the collection of medieval bells is the largest to have survived in Great Britain.
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.
