Gilles presented a delightful seminar on the influence of the Orient -- particularly the Ottomans -- on the architecture and culture of Vienna. His slides were very well prepared, and well integrated into his talk. I've been to Vienna several times, but several of Gilles' examples and comments were new to me. Really enjoyed this seminar!
Excellent presentation. Very informative and well-presented. Terrific images. The question and answer session also demonstrated the impressive extent of his knowledge and understanding.
