While shopping for new fish for our aquarium I noticed this small castle in the junk box. It is actually really detailed once you look beyond the tacky paintjob and I think it might make a fine little 6 or 10mm castle.
So far I have given it a black shading on the walls and a new base - and it looks like it will turn out alright :-). More pictures later. But not bad for 3-4£ :-).
