<s>[INST] The next text is a question of a member of the European parliament:"The Modernisation Unit at the Commission’s Directorate-General for the internal market, Industry, Entrepreneurship and SMEs decided to request clarifications from Lisbon City Council regarding Portuguese residents’ free entry to São Jorge Castle on Sundays.  That action concerns a national monument — an integral part of Portugal’s heritage and history and the responsibility for the conservation, maintenance and cultural enhancement of which the Portuguese state is clearly responsible for, along with the promotion of the population’s access to it, by any means it sees fit — and it is unusual.   There is no justification for intervention by a ‘Modernisation of the Single Market Unit’ in that process. It is, therefore, important to stress that, ultimately, the taxes (which can only be introduced by the central state in Portugal) paid by Portuguese residents finance the state in that work.   What is more, the State Budget Law provides for free entry on Sundays and public holidays to all museums and monuments for which the state is responsible.  Does the Commission plan to interfere with this national monument’s access policy?"
