The Musée des Jacobins is the town museum in Auch. It houses France's second biggest collection of Pre-Columbian art after the quai Branly, with which it has collaborated for many years. The museum garden is a 1600 square metre containing plants brought back from the Americas by the Conquistadors.
The museum was founded on 16 December 1793 and is one of France's oldest museums, housing over 20,000 objects, including 8,000 Pre-Columbian works. The building housing it, known as 'des Jacobins', was listed as a historic monument and was originally built as a Jacobin convent in the 15th century. The museum moved into it in 1979 after a major restoration project.
One of the major objects is Statue of Trajan, 1st century AD, discovered near Rome in the 18th century.

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.
