‘I love the Tagus because of the great city on its banks. I enjoy the sky because I see it from a fourth floor window in a street in the Baixa. Nothing in the countryside or in nature can give me anything to equal the ragged majesty of the calm moonlit city seen from Graça or São Pedro de Alcântara. For me no flowers can match the endlessly varied colours of Lisbon in the sunlight.’ – Fernando Pessoa, The book of disquiet
