A brief comparative analysis of this progressive event development also identifies changes in the extent and dimension with particular regard to the tourism development dimension and particularly to the cultural dimension of it. This paper is mainly attempting to answer the question regarding to what extent the public of such event has become tourist. The paper also aims to focus on more specific aspects and issues concerning the main aim by sketching a brief overview regarding the attitudes and perceptions of people regularly attending an event such the European Night of Museums in Bucharest. The paper attempts to determine the profile of participant to such event trying to identify the trends of this event on the Romanian wider market but particularly on the tourism market given the fact that museum visitor are mostly tourists.
