"..Even though Saint Jacques Tower itself is impressive, it used to be much more than just a tower. Saint Jacques Tower is the only remains of what used to be the former church of "Saint Jacques la Boucherie" -- "Saint James of the Butchery". The name of the church originates to the fact that the church lied close to and served many butchers of Les Halles, a nearby large market which no longer exists, and due to its close proximity to a major slaughterhouse."
