In the castle at Nuremberg there is an old double chapel of this sort, but it does not appear in this instance that there was an opening between the two; if it existed, it has been stopped up. There is another at Eger, and two are described by Puttrich in his beautiful work on Saxony: one of these, the chapel at Landsberg near Halle, is given in plan and section in Woodcuts Nos. 720 and 721; and though small, being only 40 ft. by 28 internally, presents some beautiful combinations, and the details are finished with a degree of elegance not generally found in larger edifices; the other, that at Freiburg on the Unstrutt, measuring 21 ft. by 28, is altogether the best of the class, from the beauty of its capitals and the finish of every part of it. It belongs in time to the very end of the 12th, or rather perhaps to the 13th century, and from the form of its vaults and the foliation of their principal ribs, one is almost inclined to ascribe to it a later period; for it would be by no means wonderful if in a gem like this the lords of the castle should revert to their old German style instead of adopting foreign innovations. The windows are of pointed Gothic, and do not appear like insertions. Other examples exist at Goslar, where, however, there is no opening between lower and upper chapel; at Coburg, Lohra, Steinfurt in Westphalia, and Vianden in Luxemburg. [Illustration: 720.

Scale 100 ft. to 1 in.] Returning again to Switzerland, with which this chapter began, we find several interesting buildings in that country during the whole round-arched Gothic period, many combining the boldness of the Northern examples with a certain amount of Southern elegance of feeling in the details, which together make a very charming combination. Among these, none are more remarkable than the cathedral at Zurich (Woodcut No. 722). Its date is not correctly known; for though it seems that a church was founded here in the time of Otho the Great, it is very uncertain whether any part of that building is incorporated in the present edifice, the bulk of which is evidently of the 11th or 12th century. The arrangement and details of the nave are so absolutely identical with those of San Michele at Pavia, that both must certainly belong to the same epoch. But in this church we meet with several German peculiarities to which attention cannot be too frequently drawn by those who would characterise correctly the peculiarities of German Gothic.
