The mother house of the Carthusians sits in a high closed valley north of Grenoble, the desert granted to Bruno and his companions in 1084 by Bishop Hugh of Grenoble and the lords who held the land.
Within fixed bounds no outsider may hunt, fish, graze flocks or enter as a woman, and the monks hold the whole of it. It is a lordship of silence rather than of tolls, but it is a real enclave: the order answers to Rome, is spared the crusade fortieth, and supplies bishops (Jean of Grenoble, Aymon of Tarentaise, Hugh of Lincoln, Humbert of Valence-to-be).
Who holds it
- Name
- Jancelin
- Title
- Prior of the Grande Chartreuse, head of the Carthusian order
- Since
- 1180 (not verified)
- Confidence
- medium
The usual list of priors gives Guigues II (1174-1180) and then Jancelin, prior from 1180 to 1233; we could not check this against a source in this session, so the name is given at medium confidence. The prior presides over the order's general chapter, held at the Grande Chartreuse since the 1140s.
What it holds
- The desert of Chartreuse: the closed valley round the monastery, within bounds fixed in 1084, where the monks alone have rights of land, wood, pasture and water
- Correries (lower house of the lay brothers) and the monastery buildings rebuilt after the avalanche of 1132
- Leadership of the Carthusian order through its general chapter
How it was acquired
Granted in 1084 by Bishop Hugh of Grenoble together with the local lords who held rights in the valley; the bishop fixed the bounds and banned hunting, fishing, herding and the entry of women inside them. After an avalanche destroyed the first monastery in 1132, Prior Guigues rebuilt it lower in the valley.
How things stand that morning
Held by the monks without dispute that we could pin for 1199-1200. The order is in favour at Rome: Innocent III has spared the Carthusians the crusade fortieth.
Wealth
Little cash: forest, pasture and stock farmed by lay brothers; gifts from patrons; the prestige of an order whose monks become bishops.
Threats
- Encroachment by neighbours' flocks and woodcutters on the desert
- Patrons and popes wanting Carthusians as bishops, which drains the house of its best men
Advocates and rivals
The bishop of Grenoble is the order's protector in the diocese. Neighbouring lords and villages with grazing and wood rights on the edges of the desert are the usual source of boundary quarrels (not pinned for 1200).
Places of note
- Grande Chartreuse: Mother house of the Carthusians
Where the sources disagree
Evidence: The 1084 grant and the rules of the desert are well known; we could not read a source on the prior or on the exact bounds in this session (the en.wikipedia page was refused by the fetch proxy), so the prior's name rests on the standard list.
On the map: Drawn as a 4 km disc round the monastery; the real bounds of 1084 followed ridges and streams of the Chartreuse massif and are not traced here.
