Suger's family origins are unknown. Several times in his writings he suggests that his was a humble background, though this may just be a topos or convention of autobiographical writing. In 1091, at the age of ten, Suger was given as an oblate to the abbey of St. Denis, where he began his education. He trained at the priory of Saint-Denis de l'Estrée, and there first met the future king Louis VI of France. From 1104 to 1106, Suger attended another school, perhaps that attached to the abbey of Saint-Benoît-sur-Loire. In 1106 he became secretary to the abbot of Saint-Denis. In the following year he became provost of Berneval in Normandy, and in 1109 of Toury. In 1118, Louis VI sent Suger to the court of Pope Gelasius II at Maguelonne (at Montpellier, Gulf of Lyon), and he lived from 1121 to 1122 at the court of Gelasius's successor, Calixtus II.
On his return from Maguelonne, Suger became abbot of St-Denis. Until 1127, he occupied himself at court mainly with the temporal affairs of the kingdom, while during the following decade he devoted himself to the reorganization and reform of St-Denis. In 1137, he accompanied the future king, Louis VII, into Aquitaine on the occasion of that prince's marriage to Eleanor of Aquitaine, and during the Second Crusade served as one of the regents of the kingdom (1147–1149). He bitterly opposed the king's divorce, having himself advised the marriage. Although he disapproved of the Second Crusade, he himself, at the time of his death, had started preaching a new crusade.
Suger served as the friend and counsellor both of Louis VI and Louis VII. He urged the king to destroy the feudal bandits, was responsible for the royal tactics in dealing with the communal movements, and endeavoured to regularize the administration of justice. He left his abbey, which possessed considerable property, enriched and embellished by the construction of a new church built in the nascent Gothic style. Suger wrote extensively on the construction of the abbey in Liber de Rebus in Administratione sua Gestis, Libellus Alter de Consecratione Ecclesiae Sancti Dionysii, and Ordinatio. In the 1940s, the prominent art-historian Erwin Panofsky claimed that the theology of Pseudo-Dionysius the Areopagite influenced the architectural style of the abbey of St. Denis, though later scholars have argued against such a simplistic link between philosophy and architectural form. Similarly the assumption by 19th century French authors that Suger was the 'designer' of St Denis (and hence the 'inventor' of Gothic architecture) have been almost entirely discounted by more recent scholars. Instead he is generally seen as having been a bold and imaginative patron who encouraged the work of an innovative (but now unknown) master mason.
Contribution to Architecture 
Abbot Suger, friend and confidant of the French Kings, Louis VI and Louis VII, decided in about 1137, to rebuild the great Church of Saint-Denis, the site of Coronation of the French monarch since 754.
Suger began with the West front, reconstructing the original Carolingian façade with its single door. He designed the façade of Saint-Denis to be an echo of the Roman Arch of Constantine with its three-part division and three large portals to ease the problem of congestion. The rose window above the West portal is the earliest-known such example, although Romanesque circular windows preceded it in general form.
At the completion of the west front in 1140, Abbot Suger moved on to the reconstruction of the eastern end, leaving the Carolingian nave in use. He designed a choir (chancel) that would be suffused with light.   To achieve his aims, his masons drew on the several new features which evolved or had been introduced to Romanesque architecture, the pointed arch, the ribbed vault, the ambulatory with radiating chapels, the clustered columns supporting ribs springing in different directions and the flying buttresses which enabled the insertion of large clerestory windows.
The new structure was finished and dedicated on 11 June 1144, in the presence of the King. The Abbey of Saint-Denis thus became the prototype for further building in the royal domain of northern France. It is often cited as the first building in the Gothic style. A hundred years later, the old nave of Saint-Denis was rebuilt in the Gothic style, gaining, in its transepts, two spectacular rose windows.
Suger became the foremost historian of his time. He wrote a panegyric on Louis VI (Vita Ludovici regis), and collaborated in writing the perhaps more impartial history of Louis VII (Historia gloriosi regis Ludovici). In his Liber de rebus in administratione sua gestis, and its supplement Libellus de consecratione ecclesiae S. Dionysii, he treats of the improvements he had made to St Denis, describes the treasure of the church, and gives an account of the rebuilding. Suger's works served to imbue the monks of St Denis with a taste for history and called forth a long series of quasi-official chronicles.

- When the new rear part is joined to that in front,
The church shines, brightened in its middle.
For bright is that which is brightly coupled with the bright
And which the new light pervades,
Bright is the noble work Enlarged in our time
I, who was Suger, having been leader
While it was accomplished.

- Erwin Panofsky argued that Suger was inspired to create a physical representation of the Heavenly Jerusalem, however the extent to which Suger had any aims higher than aesthetic pleasure has been called into doubt by more recent art historians on the basis of Suger's own writings.
