Real Estate / Is there a property tax in Poland? [3]

Hi all, my father passed away and I inherited some farm land in Poland. We haven't been there in 20 years but my uncle has been maintaining the property, buildings and machinery. Are there any costs associated with keeping it, like a property tax? What do I need to do to make sure they government does not consider it abandoned? Can I rent it so it generates some sort of income? I'm not really sure where to start so any info would be greatly appreciated.
