Please help me ID this...castle and gates We've been given boxes after boxes of LEGO bricks...trying to piece them all together.  It's a blessing but also a great challenge !
That would be Attack On Weathertop, from the Lord Of The Rings series. Looks like it's missing a fair few pieces, but it's still mostly intact.

EDIT: Oops, top picture didn't load before I posted. The gate is from Mines Of Moria; the fold-out hill is Attack On Weathertop.
