Abbey of Longchamp
Though betrothed to Hugh, eldest son and heir of Hugh X of Lusignan, Isabelle refused to celebrate the formal wedding due to her fixed determination to remain a virgin, although she never became a nun.
In furtherance of Isabelle's wish to found a monastery of Poor Clares, her brother King Louis IX of France began in 1255 to acquire the necessary land in the Forest of Rouvray, not far from the Seine, west of Paris. On 10 June 1256, the first slide of the monastery church was laid. The building appears to have been completed about the beginning of 1259, because Pope Alexander IV gave his sanction on 2 February 1259, to the new Rule which was composed especially for this monastery by the Franciscan Mansuetus base on the Rule of St. Clare. Not as strict as that rule, the community was allowed to hold property. The monastery was named the Monastery of the Humility of the Blessed Virgin. In the Rule the nuns were called the Sisters of the humble order of servants of the most Blessed Virgin Mary. The nuns were subject to the Friars Minor. Some of the first nuns came from the Poor Clare monastery in Rheims.
Isabelle never joined the community herself, but did live in the monastery, in a room separate from the nuns’ cells. She suffered from illnesses during her life, which prevented her from following the rule of life for the nuns. Isabelle refused to become abbess, which allowed her to retain her wealth and resources, so she could support them and continue to give to the poor. She kept a discipline of silence for most of her day.
Isabelle died at Longchamp on 23 February 1270, and was buried in the monastery church.

The Abbey of Longchamp had many vicissitudes. At the time of the French Revolution, on 26 February 1790 the nuns were served with an order of expulsion, but it was on 17 September 1792 that the valuables and sacred objects were taken away from the chapel and by 12 October that year the nuns had left the monastery.. In 1794 the empty building was offered for sale, but, as no one wished to purchase it, it was destroyed. In 1857 the walls were pulled down, except for one tower, and the grounds were added to the Bois de Boulogne.
