Public aid can be involved even in such peculiar public activity sector as culture and heritage conservation. Hence, the EU projects implemented in this area may be subject to legal restrictions on state aid. In this respect, particular legal doubts concerning state aid arise in the context of “impact on trade” premise. This situation is a consequence of both lack of clear definition thereof and the peculiar nature of culture projects. The present paper is aimed at identifying particular issues that ought to be taken into account when determining the possible impact on trade (recommendations for judicature). These issues aren’t actually defined in law, but only in few judgments and literature. Hence, there is a necessity to make further researches.
