I just built up my copy of 6034 Black Monarch's Ghost, which I won from ebay.
It is quite a fun little set and I really like the knight that comes with it.
But what I would like to know is, on each side of the small door bit, there is one of these (one of which has a technic pin in)
I was just wondering, does this mean that the older castle sets joined up to form a larger layout or something? Are there other sets which are like this?
Thanks,
Jon.
