All very well written and illustrated. Perhaps some of the 'history' was a little 'contrived', i.e. the successes and achievements of the certainly key protagonists slightly embellished, and the selection of a distinctly pedestrian monument to Otto, the second last, pointless! More on the classic architectural, perhaps even planning and development of the old city, would have been very welcome. Otherwise, it was great and the quizzes interesting and fun.
