this upper floor, and the chambers all open to the church with arches, and have traceried windows in their outer walls. The transverse section of the nave is therefore novel, and unlike any other with which I am acquainted, and interested me not a little. The exterior is, perhaps, less interesting than the interior. The chevet is fine, but with nothing in any way unusual in its design; the upper part of the buttresses is destroyed, and the walls finish without parapet or roof, so as to make the church look somewhat like a roofless ruin. The steeples are quite plain below their belfry stage, under which are arcaded string-courses; the belfry stages themselves are richly panelled and pierced, and surmounted by pierced parapets. They are not perfectly octagonal in plan, the cardinal sides being the widest, and their height from the floor of the church is as nearly as I could measure 179 ft. 6 in., whilst their external diameter is about 30 feet. It is on ascending these towers that one of the greatest peculiarities of the Barcelonese churches is seen; they are all roofless, and you look down on to the top of their vaulting, which is all covered with tiles or stone neatly and evenly laid on the vault, in such a way as effectually to keep out the weather. The water all finds its way out by the pockets of the vaults, and by pipes through the buttresses with gurgoyles in front of them. Everything seemed to prove that this was _not_ the old arrangement, for it is pretty clear that the walls had parapets throughout, and that there were timber roofs, though I saw no evidence as to what their pitch had been. The present scheme, ugly and ruinous as it looks--giving the impression that all the church roofs have been destroyed by the fire of the fortresses above and at the side of the city--seems nevertheless to have solved one of those problems which so often puzzle us--the erection of buildings which as far as possible shall be indestructible. There is now absolutely no timber in any part of the work; but it is of course questionable whether a roof which endures the test of a Spanish climate, with its occasional deluge of rain succeeded by a warm drying sun, would endure the constant damp of a climate like ours. But at any rate the makeshift arrangement which is universal here is very suggestive. The flying buttresses are insignificant, owing to the small height of the clerestory.
