Segovia cathedral
An excerpt from GE Street's book on Spanish Gothic
Segovia cathedral is a building of no little value in the history of Spanish art, as being perhaps the latest Gothic building erected, and one which was yet but little influenced by Renaissance art.
The plan of this church must be compared with that of the new cathedral at Salamanca, built by the same man [Juan Gil de Hontañon]. The details of the two churches are very similar; but the scale of Segovia is slightly greater than that of Salamanca, and it has the enormous advantage of having a grand chevet in place of a square east end. The internal effect is undoubtedly very noble, in spite of all the shortcomings which must be looked for in a work of such a date. 
The main columns are of grand dimensions, moulded, and rising from lofty bases planned with that ingenious complication of lines which was always so much affected by the later German and Spanish architects. The arches are very lofty, and there is no triforium, but only a traceried balustrade in front of the clerestory, which consists of uncusped triplets filling the wall above the springing of the groining, and very low in proportion to the great height of the church, though at the same time amply sufficient for the admission of all the light necessary in such a climate. The aisle has a somewhat similar clerestory, but without the traceries balustrade which we see in the nave clerestory, and the aisles and chapels are all lighted with windows, each of one broad light. Most of the smaller arches here are semi-circular; but though this is the case, and though so many of the windows are of one light, there is no appearance anywhere of any attempt to revive the form or detail of earlier work.
On the exterior the general character is just the same as that of Hontañon's work at Salamanca. There are the same pinnacles and buttresses, the same parapets, and the same concealment of the roofs and roof-lines everywhere – even in the transepts, which have no gables – and there is also a domed lantern over the Crossing and a lofty tower at the west end, finished with an octagonal stage covered with a dome, and rising from between four great pinnacles. So great, in short, are all the points of similarity, that I can well believe that portions of the two works may have been executed from the same plans, and this close copying of the earlier work at Salamanca may have been the true reason of the respectably Gothic detail of the chevet, built as it was so near the end of the sixteenth century. The groining is all of the kind so common in Spain, having ogee lierne ribs in addition to the diagonal, and in place of ridge ribs.
With all its faults this church has grand points: this every one will allow who has seen it rising in a noble pyramidal mass above the houses of the town from the open space in front of the Alcazar, from whence all its parts are seen to great advantage.
