The Cathedral of Saint-Pierre in Poitiers is a very early Gothic hall church. It may have been planned and built at the instigation of the royal couple, Eleanor of Aquitaine and Henry II

There has been a cathedral in Poitiers since Hilary of Poitiers was elected the first bishop in mid 4th century. However, in its present version, the Cathedral in Poitiers is a hall church with three aisles and two barely projecting transepts. The nave is nearly 94 m long and 30 m wide. The vaults rise 27 m. The nave is covered with a single roof, supported by huge buttresses. It has a flat chevet embellished with three apsidioles. Here, at the eastern end of the clerestory, a series of important stained windows have been preserved. The English king, Henry II, and Eleanor of Aquitaine, married in the old Cathedral of St. Pierre in Poitiers, and probably prompted the church’s construction. Unfortunately, the Cathedral’s archive was destroyed during the Hundred Year’s War, and the precise details are unknown. However, according to a notice from 1525 [1], Henry II rebuilt the city walls in 1161, and, likely, the royal couple was directly involved in the design of the new Cathedral, which was undertaken at this time. Later, from 1167/68 – 1174 – after the estrangement of Eleanor from Henry – she was frequently in residence in Poitiers..

Jean Belmain from York possibly exerted a special influence. As Henry II’s personal choice, he was appointed bishop in Poitiers. Early on in his career, the new bishop had won royal favour. He probably supervised the cycle of stained glass windows, which Henry and Eleanor of Aquitaine are well-known to have donated to the church and which partly still dominates the eastern end. The couple may be seen at the bottom of the large window depicting the crucifixion. The small scene shows Eleanor and Henry with their four boys in the background. As John is included, this part of the window must have been commissioned after the birth of John in 1166 but before the estrangement between the royal couple. The window which they hold is the result of a 19th-century restoration.

The cycle of windows is no longer intact. Thus, it is known that there was a window telling the story of Noah, and fragments may be found in the Cloister’s collection in New York. [2] However, despite pillage and destruction in the 100-years war and during the Wars of Religion, the Cathedral still holds the central part – the Crucifixion and Ascension above the altar, flanked by a Life of St. Lawrence and Lives of SS Peter and Paul. Other stories are told in now highly fragmented windows in the northern and southern parts of the choir and in the transepts. The style of the windows belongs to the tradition of Western France. A careful study of the iconographic models has revealed that they seem to derive from Late Antique sources transmitted through English manuscripts, which inspired the artists via an atelier in Bourges. It is probable that the adherence to these aesthetic conventions also inspired the basics of the new “Gothic” Cathedral – the hall.
However, the extent to which the royal couple was responsible for any comprehensive artistic and architectural ‘programme’ in Poitiers is still highly debated. [3]

One reason for the not-very-elegant outlook of the Cathedral is the fact that it took a very long time to complete. Thus, inspiration for the façade may have come from both Notre-Dame in Paris and the Cathedral in Bourges, while the portal with the Judgement is reminiscent of the one in Amiens. To the north, the portal depicts the Coronation of the Virgin, while the southern portal tells the story of St. Thomas. Building the Cathedral in its present form took over a hundred years. The first phase covered the eastern end, while Maurice de Blason initiated the second part. Finally, work reached the western end c. 1230. However, it was not until 1290 that the upper nave and vaults were completed. It was finally consecrated in 1379; however, even then, it was considered unfinished. Some sources indicate that the very long process of building the Cathedral was perhaps the result of the general impoverishment which the civil wars in the late 12th and beginning of the 13th centuries brought about in the city and the region [4]
A unique feature is the magnificent choir stalls from the 13th century, wA notable feature of the church is its magnificent choir stalls, which date back to the 13th century and are considered the oldest in France. These were installed by Bishop Jean de Melun, who served from 1235 to 1257. It is likely that the recently discovered murals are from the same period.
