Architecturally, St Mary's Church was one of the most ambitious churches in the county. It is in the Decorated style with a prominent, integral, tower. The church was originally dedicated to St Leonard, until the mid-nineteenth century restoration. The porch, of the fourteenth/fifteenth centuries, has buttresses which display gargoyles and pinnacles.
The interior contains interesting, nineteenth-century, stained glass, including The Good Shepherd by Kempe & Co of 1930–31.
Next to the church stands The Procurator's House, a sixteenth house, now ruined, which belonged to the vicarage of Magor.
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.
