Gabriel is ridiculously knowledgeable about the history of the region in general and the city specifically. He had a wealth of information, supplemented with a book of pictures that had been prepared, and was also able to answer pretty much all the questions that everyone had. The tour was very focused on history, whereas I tend to be more interested in what things are like currently, but that wasn't an issue for me because he was also able to speak to that in response to our questions - both about how the things he described impacted life today, and other questions about his thoughts on the current situation in Sighișoara and Romania in general.
