Horrible Histories Gruesome Guides
Previously Horrible Histories Cities
Some Horrible Histories have been based around a particular city, rather than a nation or a specific time period. They also have a map when the front cover is folded out, and explain some structures in the city when the back cover is folded out. Therefore, many people consider them to be a sub-series as well. (Even though Loathsome London doesn't have these qualities, it was included into this sub-series during the republishing of the series from 2008 to 2011.[1][2]
