Wildrover that military museum sounds awesome
Well i spent a good few hours there... They have lots of suits of armour and weapons from the tuetonic knights era ,second world war stuff , both Polish and german , and outside Russian aircraft , tanks and armoured vehicles...
The museum is in the centre of town , and not far from it i found an outside market where i bought an German iron cross for not so much money...
While you are in Ko£obrzeg you can have a pleasure cruise on the baltic , and enjoy all the usual stuff of a seaside holiday resort...
I recommend you buy yourself a book called rough guide to Poland , you can look up whatever town you are in and see what attractions are there , as well as seeing where all the local resteraunts , pubs and nightclubs are , its also got lots about Poland generally , and includes lots about the culture and such things..
