Historic Problems with the film
Just having a little fun.
The School itself. Spanish style in New England?
School is over 300 years old? From 1973 that would be around 1673. There wasn't even an established country let alone a school(and all girls hmmm girls did not atend school at that time).
When the Head Mistress gives Elizabeth a latern to keep in her room. (they are far away from the main power lines. How big do the think Salem is? It's a pretty small town cramped as well.
There was a legend of a Witch being hung in a celler. Would be hard to hand anyone from a cellar in any house in New England dating before the early 20th centure. Many homes cellars were less then 4 feet high.
