This is the second edition of the Portuguese version of the Calouste Gulbenkian Museum Guide, which was published for the first time in 2004. This new edition, which retains the structure of the first edition and features the same selection of pieces, has a new cover and content that has been revised and updated by those in charge of the respective sections of the Calouste Gulbenkian Collection. Portuguese-speaking visitors to the museum can therefore benefit once again from a guide that examines the main works of art that make up the Gulbenkian collection and provides up-to-date and rigorous information on these works.
