A large outdoor flea market held each weekend from dawn till dusk, in Koło - an outlying district northwest of the centre. Attracting buyers and sellers from across the country this is exactly the place if you’ve ever wanted to own a Prussian helmet or set of palace doors from India (yours for 16,000zł). What else can you find? We’ve spotted pre-war posters advertising Polish toothpaste, early 19th century postcards, prewar bathroom fixtures and grandfather clocks. Vinyl records go for as little as 1zł. The golden rule is to haggle at all times. Paying the asking price means overpaying.
