Cardinal Richelieu would without doubt had good use of an assassin in the french court in 1622.
Lots of swordfights, musketeers and some guns, like in AC2.
You want architecture, try Paris ?
This was the absolute hotbed of political intrigue at that time for all Europe, and the factions fought about power,money,land,religion and the class difference were enormous.
Allied countries became enemies, allies and enemies again sometimes the same year and royal weddings was often the last tool to make bonds between countries.
Very interesting times.
( weak ruler with several "advisors", war on several fronts ,bad economic times for the people and good for the wealthy.... this reminds me of something...hmmm.It ended in revolution, i wonder how it ends this time. )
