The Museum of Sacared Art and Archaeology, part of Porto's Seminário Maior de Nossa Senhora da Conceição, is housed in a 17th Century wing of the former Jesuit College. The museum's remarkable, rich and varied treasures are accommodated in a dynamic and artistically vibrant space that is open to the community and engaged in conserving and communicating the collection. What was once known as the 'corridor of slate' is now a noteworthy gallery of religious sculptures dating back from the 13th to 19th centuries. Sculpture is the true speciality of this museum, as can clearly be seen in the Irene Vilar room. Nevertheless, fascinatingly exceptional examples of painting, illuminated manuscripts, jewellery, vestments, religious adornments and archaeology are also to be found here.
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.
