The Cathedral Church of Our Lady of Sorrows, also known as St Mary's Cathedral or Wrexham Cathedral, is a Roman Catholic cathedral in Wrexham, Wales. The cathedral was originally built as a parish church in 1857. Its architect, Edward Welby Pugin, adopted a 14th-century Decorated Gothic style. The church replaced an earlier chapel, located in King Street, which by the 1850s was deemed insufficient for the growing congregation, and finance was provided by a local industrialist. Further additions to satisfy a still-growing congregation were made in the mid-20th century, in the form of the cloister and side chapel.
The church was designated a pro-cathedral in 1898 upon the establishment of the Roman Catholic Diocese of Menevia. It was consecrated on 7 November 1907.
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.
