The town occupies a strong position and commands the pass, hence it was occupied as a fortress by the Allobroges from early times. Afterwards an important city under the Romans (as already mentioned in [Part IV.]), it continued so during the Middle Ages. But it suffered severely from the attacks of invaders, being first ravaged by the Lombards, and afterwards by the Saracens.

In the ninth century Boson, King of Burgundy and Provence, made Vienne his capital. After the fall of that kingdom, the city declined, and became the possession of the Dukes of Albon, who governed under the title of Dauphins of Viennois, till 1349, when Humbert II. ceded the country to the King of France.

FIG. 37. ST ANDRÉ-LE-BAS, VIENNE.

The towers of the two most ancient churches, viz., St André-le-bas and St Pierre (Figs. 37 and 38), are very fine examples of the campanile-like designs of the South, and strikingly resemble that of the Ainay at Lyons. The former is ornamented with the arcading so characteristic of the churches of the Rhine and Lombardy, some of the miniature arches resting on corbels carved with grotesque heads. The tower of St Pierre has the large trilobed arch, also common in the region to the eastward.

St Pierre is very ancient and shews masonry constructed somewhat after the Roman manner, with courses of brickwork dividing the rubble. The west entrance is preceded by a porch or narthex in an early style.

St André-le-bas was the chapel of the Duke of Burgundy. This church has a single nave (in the style of the south-west provinces), with groined vaulting and heavy buttresses, but the interior has been completely restored. An inscription fixes its date as 1142. There are also some remains of a fine cloister adjoining.
