The estate was first mentioned in 1466. It has been associated with the Gilsens, von Rosens, von Zoeges, von Benckendorffs, von Krusensterns and von Uexküll-Güldenbandts. The ruins of a vassal castle destroyed during the Livonian War were reconstructed as a stately castle in the 17th to 18th centuries, which received its present form in 1790.
For many years, the manor was the home of a world famous explorer and mariner Adam Johann von Krusentern, who also passed away in Kiltsi. Since the 1920s, the manor houses a school. The building has been thoroughly restored starting in 2000.
the mansion can be rented for celebrating birthdays and weddings, organizing trainings and seminars, and in summer you have the opportunity to visit the mansion.
The historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
