Ste Marguerite de la Foret (Forest church) is the smallest parish church in Guernsey. It was built in two stages with the nave, chancel and the centrally positioned tower in the 13th century and additions in the 15th century. Interestingly it has two entrances, one originally for men and the other for women. All now enter by the north door. Its walls feature massive stones which were once part of a dolmen. The Church originally served the small community at Le Bourg. The inside of the Church was restored in 1891. The Church clock commemorates Queen Victoria's Diamond Jubilee. The churchyard has indications that it was an ancient burial ground.
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.
