The Twins - Almost Right

I don't think the twins knew about the monster either, but I 
wonder if they knew about the passage that led to the Chamber. When 
they gave Harry the Marauders' Map to sneak out to Hogsmeade there 
were 5 tunnels. Filch knows about 3 and 1 'caved in' the year before,
leaving the one that goes to Honeydukes' cellar that Harry used. I 
wonder if the caved in tunnel wasn't the one that led to the 
chamber.... it caved in the same year Harry rescued Ginny from there 
(and Lockhart had his memory wiped in that failed spell).
