whats a nice, sturdy wooden castle for DS (5)?

[cats07]

Any recommendations ladies? Something that's not going to fall to bits if it's moved from one side of the room to the other, or if DS2(1) takes an interest.

Thank you.

We have this one - I am VERY strict about them moving it though, because although it is sturdy, the wood would split if pulled to pieces too many times. But I have an 8 year old, a 6 year old and a 3 old and it is in perfect condition still.

thank you LilyB - it looks great. I like the idea of the crane and working drawbridge as these are exactly the kind of things DS loves working! And it's quite nice looking, so I won't get fed up looking at it after 2 months.
