Domaine de Charance near Gap in Hautes-Alpes preserves a dramatic landscape where a 12th-century fortress sits at altitudes between 1,000 and 1,903 metres across 220 hectares. From the 10th century, a fortified castrum occupied these heights before the Bishop of Gap acquired the domain in 1309, establishing the terraced gardens that characterize the estate. The bishops maintained ownership through the French Revolution, after which the château was looted, rebuilt multiple times, and auctioned as national property. Today, the administrative offices of Écrins National Park occupy the restored château since 1973. The standout feature is the 9,000-square-metre terraced garden, designated a Remarkable Garden in 2005, featuring fountains, canals, a collection of 1,000 rose varieties, and historic fruit trees that reflect centuries of horticultural refinement.
