A cloister of exceedingly handsome design and arrangement is attached to the cathedral, where it is said the _mâchicoulis_ is the most ancient known. This feature is also notable in the roof-line of the nave, which, with the extraordinary window piercings and their disposition, heightens still more the suggestion of the manner of castle-building of the time. The functions of the two edifices were never combined, though each--in no small way--frequently partook of many of the characteristics of the other. Aside from this really beautiful cloister, and a rather gorgeous, though manifestly good, painted altar-piece, there are no other noteworthy accessories; and the interest and charm of this not really great church lie in its aspect of strength and utility as well as its environment, rather than in any real æsthetic beauty. [Illustration: _St. Nazaire de Béziers_] XII ST. NAZAIRE DE BÉZIERS St. Nazaire de Béziers is, in its strongly fortified attributes of frowning ramparts and well-nigh invulnerable situation, a continuation of the suggestion that the mediæval church was frequently a stronghold in more senses than one. The church fabric itself has not the grimness of power of the more magnificent St. Cécile at Albi or Notre Dame at Rodez, but their functions have been much the same; and here, as at Albi, the ancient episcopal palace is duly barricaded after a manner that bespeaks, at least, forethought and strategy. These fortress-churches of the South seem to have been a product of environment as much as anything; though on the other hand it may have been an all-seeing effort to provide for such contingency or emergency as might, in those mediæval times, have sprung up anywhere. At all events, these proclaimed shelters, from whatever persecution or disasters might befall, were not only for the benefit of the clergy, but for all their constituency; and such stronghold as they offered was for the shelter, temporary or protracted, of all the population, or such of them as could be accommodated. Surely this was a doubly devout and utilitarian object. In this section at any rate--the extreme south of France, and more particularly to the westward of the _Bouches-du-Rhône_--the regional "wars of religion" made some such protection necessary; and hence the development of this type of church-building, not only with respect to the larger cathedral churches, but of a great number of the parish churches which were erected during the thirteenth and fourteenth centuries.
