Conspiracy !

[Peter Pedant]

in 1688, at a time when James II was obviously on his way out, a group of people (in favour of William of Orange) conspired in a room with a window in each of the four walls-so they could see if anyone was listening.

Does anyone know the name and location?

[Personica]

It is known as the Rye House Plot, by The Immortal Seven. Go to http://en.wikipedia.org/wiki/James_II_of_England

Though I couldn't find the location, it was probably The Houses of Parliment
