The principal group of churches in the district is found at Lubeck, which was perhaps, in the Middle Ages, the wealthiest town on the shores of the Baltic. The largest of these is the Dom Kirche or Cathedral (Woodcut No. 769), a building 427 ft. long over all. The nave is 120 ft. wide externally. The vaults of the three aisles spring from the same height, the central one being 70 ft. high, those of the side-aisles a little less. This, with the wide spacing of the piers, gives a poor and bare look to the interior. The choir is better, showing a certain amount of variety about the chevet; but even this is leaner than in any stone building, and displays all the poverty so characteristic of the style. The Marien Kirche is a more favourable specimen of its class, though not so large. It is of a somewhat earlier age, and is built more in accordance with the principles of Gothic design. The central aisle is 130 ft. high; the side-aisles only half as much. This allows space for a very splendid clerestory, which, if filled with stained glass, would redeem the flatness of the mouldings and the general poverty of the architecture of the interior. [Illustration: 771. View of Marien Kirche, Lubeck. (From Schlösser and Tischbein.)] The church of St. Catherine is smaller than either of these, though of about the same age as that last mentioned, and of as good a design. It possesses the somewhat curious peculiarity of having a double choir one above the other like that of St. Gereon at Cologne (Woodcut No. 740), but more complete and extensive than in that example. The whole of the lower choir is vaulted over, and a second, at a height of 20 ft., forms an upper choir over its whole extent. There are several smaller churches in Lubeck, none of which show any peculiarities not found in the larger. The same faults which characterise the interior of these churches are also found in the exterior. The Marien Kirche (Woodcut No. 771) is the best of them in this respect, but though its outline is good, it is far from being a pleasing specimen of architecture. Its two western towers are of the form typical in Lubeck. They are just 400 English ft. in height, and with these dimensions ought to be imposing objects, but they certainly are not so, being in fact as bad specimens as could be of Gothic towers. As usual in Germany, there is no door at the west end of any of these churches, and the principal entrances are in all cases lateral; one of those attached to the cathedral is an elaborate and beautiful piece of stone architecture, but it is the only one apparently that is at all remarkable. Some of the rood-screens are covered with carving, and the tabernacles, or receptacles for the holy elements, are, as in most parts of Germany, elaborately ornamented. They are nearly of the same age and of the same style as those at Nuremberg, one of which is represented in Woodcut No. 762.
