We visited the Alcazhar on a Monday which meant we only had to pay a small fee to see the camera obscura, seeing the rest of the Alcazhar was free. Both the lady who greeted us and the guide who demonstrated the camera obscura were very helpful and spoke good English. We visited shortly after opening and enjoyed the peacefulness wandering around as there were only a few other tourists at this time before a louder group of Spanish tourists arrived. The pharmacy and olive press as well as the Roman baths were interesting. The demonstration of the camera obscura was in English by a knowledgeable guide who made the experience very interesting, whilst I am sure she had explained this many times it felt fresh and not just a rehearsed script. She made Jerez come alive and I feel this would be a perfect start to anyone visiting Jerez as following the panoramic visual tour tourists could then go and visit some of the sites viewed. Many thanks to our lovely guide.
