The situation of it is extremely commanding, and therefore very beautiful. It is built upon a rock which overhangs the Loire, all the castles upon this river being built with the evident purpose of controuling and commanding the navigation. What first struck us very forcibly was the variety and evident dissimilarity of the several parts. This circumstance was explained to us by our guide, who informed us that the castle was the work of several princes. The eastern and southern fronts were built by Louis the Twelfth about the year 1520, the northern front was the work of Francis the First, and the western side of Gaston, duke of Orleans. Every part accordingly has a different character. What is built by Louis the Twelfth is heavy, dark, and gothic, with small rooms, and pointed arches. The work of Francis the First is a curious specimen of the Gothic architecture in its progress, perhaps in its very act of transit, into the Greek and Roman orders; and what has been done by Gaston, bears the character of the magnificent mind and bold genius of that great prince. This comparison of three different styles, on the same spot, gave me much satisfaction. The rooms, as I have said, such as were built by Louis the Twelfth, are small, and those by Francis spacious, lofty, and boldly vaulted. Nothing astonished me more than the minor ornaments on the points of the arches; they were so grossly, so vulgarly indecent, that I was fearful the ladies might observe me as I looked at them: but such was the taste of the age. Others of the ornaments were less objectionable: they consisted of the devices of the several princes who had resided there. We were shewn the chamber in which the celebrated Duke of Guise was assassinated, and the guide pointed out the spot on which he fell. A small chamber, or rather anti-chamber, leads to a larger apartment: the Duke had passed through the door of this anti-chamber, and was opening the further door which leads into the larger apartment, when he was assassinated by order of Henry the Third. His body was immediately dragged into the larger apartment, and the king came to view it. "How great a man was that!" said he, pointing to his prostrate body. Historians are still divided on the quality of this act, whether it is to be considered as a just execution, or as a cowardly assassination. Considering the necessary falsehood, and breach of faith, under which it must have been perpetrated, the moralist can have no hesitation to execrate it as a murder.
