Lombardy in the Romanesque period was thoroughly under German influence, and the buildings remaining to us from the eleventh and twelfth centuries bear a close resemblance to those erected north of the Alps at the same date. The twelfth century Lombard churches again are specimens of round-arched Gothic, just as truly as those on the banks of the Rhine. Many of them are also peculiar as being erected chiefly in brickwork; the great alluvial plain of Lombardy being deficient in building-stone. St. Michele at Pavia, a well-known church of this date, may be cited as a good example. This is a vaulted church, with an apsidal east end and transepts. The round arch is employed in this building, but the general proportions and treatment are essentially Gothic. A striking campanile (bell tower) belongs to the church, and is a good specimen of a feature very frequently met with in Lombardy; the tower here (and usually) is square, and rises by successive stages, but with only few and small openings or ornaments, to a considerable height. There are no buttresses, no diminution of bulk, no staircase turrets. At the summit is an open belfry-stage, with large semicircular-headed arches, crowned by a cornice and a low-pitched conical roof.[25] In the same city a good example of an Italian Gothic church, erected after the pointed arch had been introduced, may be found in the church of Sta. Maria del Carmine. The west front of this church is but clumsy in general design. Its width is divided into five compartments by flat buttresses. The gables are crowned by a deep and heavy cornice of moulded brick and the openings are grouped with but little skill. Individually, however, the features of this front are very beautiful, and the great wheel-window, full of tracery, and the two-light windows flanking it, may be quoted as remarkable specimens of the ornamental elaboration which can be accomplished in brickwork. The campanile of this church, like the one just described, is a plain square tower. It rises by successive stages, each taller than the last, each stage being marked by a rich brick cornice. The belfry-stage has on each face a three-light window, with a traceried head, and above the cornice the square tower is finished by a tall conical roof, circular on plan, an arrangement not unfrequently met with.
