The Château de Picomtal, in Crots (Hautes-Alpes), was built in the Middle Ages and renovated in the 16th and 19th centuries. A full restoration in the early 2000s revealed writings by Joachim Martin, documenting 19th-century village life.
Originally a feudal residence, the château expanded over centuries, surviving fires and multiple owners. It was listed as a historic monument in 1989. Restored between 1999 and 2003, it now serves as a guesthouse and event venue.
It features a chapel with 1892 frescoes and a Provençal-style garden, awarded the 2015 National Garden Prize.
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.
