It will be obvious, it is hoped, that in the selection of subjects for illustration, an endeavour has been made to avoid in any wise trenching upon or clashing with those already fully treated in the admirable work on Spanish Ecclesiastical Architecture by Mr. G. E. Street. Whilst he has turned from, I have turned towards, the Plateresque and later styles of Spain, and whilst he has sought specially for what might be useful to church-builders, my aim has been rather to collect hints for house-builders. Thanks to him, and others like him, we have now been left with more to learn in the latter direction than in the former. The following was my line of tour, and as it comprises most of what is, I believe, best worth seeing in Spain in the way of Art, with the notable exceptions of Santiago, Oviedo, Murcia, Cuenca, Placencia, Alicante and Valencia, which want of time did not permit me to include, I do not hesitate to commend it to those, desirous, as I was, of seeing as much as possible of what was excellent or curious within a short space of time. It was as follows, from London via Paris, Bordeaux, and Bayonne to Spain, beginning with Burgos, then successively visiting Valladolid (rail), Venta de Baños (rail), Leon (rail), Zamora and Salamanca, (by "diligence" from Leon) Avila (by "diligence" from Salamanca) Escorial (rail), Madrid (rail), Segovia (by "diligence" from Madrid and back), Alcala de Heñares (by rail from Madrid and back), Toledo (by rail from Madrid and back), Cordoba (rail), Sevilla (rail), Cadiz (by the Guadalquivir steamer), Gibraltar (by steamer), Malaga (by steamer), Granada (rail and "diligence,") Andujar ("diligence,") Madrid (rail), a second time, Guadalajara (rail), Saragossa (rail), Lerida (rail), Barcelona (rail), and Gerona (rail), thence to the frontier by "diligence," and home by rail, viâ Perpignan, Carcassonne, Toulouse and Paris. To preserve some sort of order, I have arranged my sketches as they were executed in point of time, and thrown my notes into a corresponding sequence. To assert that Spain can teach the lessons to the architect which may be gained from Italy, or even from France would, I think, be to claim too much for her, but on the other hand, it should be remembered, that it is a mine which has been very much less exhausted. To the interest and grandeur of its Northern Gothic buildings, Mr. Street has done a justice long denied to them; while Girault de Prangey, and above all Owen Jones, have helped us to a right appreciation of the works of those masterly artificers, the Moors, who seem to have possessed an intuitive love for the beautiful in structure. It is with no small pleasure that I have laboured to direct attention to other monuments, than those they have so satisfactorily illustrated, of a land from travelling in which I have derived great delight, and much instruction.
