This is the south façade of what is called the logis at Montrésor, on high ground above the little Indrois River (a stream, really). The logis was built at the beginning of the period known as the French Renaissance, which covered the 16th century. Châteaux including Chambord, Chenonceau, and many others were being built (or improved, expanded, and otherwise modified) all over the Loire Valley. It's interesting to note that the weather in France during what became known as the Renaissance was much warmer than it had been over the two previous centuries. There must be a connection between these two facts.
The Robert-Collins bilingual dictionary translates logis as home, dwelling, or abode. The French term is obviously related to the English term lodgings or lodge. This one qualifies as a mansion, and it was built starting at the end of the 15th century (1490 or so) within the walls of the old medieval fortifications, which were falling into ruin at the time. Fortified châteaux were no longer needed, since the 100 Years War (1337-1453) between the French and the English nobility had ended. Wealthy people started building fine, more comfortable residences for themselves.
