The Compesières Commandry is the main Commandry of the Order of Malta in the Canton of Geneva in Switzerland. The village of Compesières existed since the 12th Century and was also mentioned as the family name of the local noble family. In 1270 the Bishop of Geneva, Aymo of Menthonay, granted the village church to the Order of Saint John. They then expanded the church into a Commandery. It is likely that the oldest parts of the castle date from this period. The current castle was built in the 15th century. It was used by the Order as a hospice for pilgrims, hospital and a military saltpeter factory. In 1536, during the Protestant Reformation, the Commandry was stripped from the Order. The order returned to the castle in 1564, but it was held by the Protestant leaders of Geneva and Bern until a treaty between Geneva and Savoy returned it completely in 1598.
The order continued to hold the Commandry until the 1882, when it was transferred to the municipality of Bardonnex. In 1955, the municipality gave one of the rooms in the castle to the Order of Malta to build a museum.
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.
