Catalogue of the BAQ 2018. "For the first time the XXI edition of the Quito Biennial opened an academic call for universities and professionals, and it is in the Biennial Week where the results will be shown in three different moments: the Academic Exhibition, the discussions/debates and the Academic Catalog. A remarkable emphasis has been placed on the importance of architectural criticism in the process of thought and knowledge. We have invited prestigious critics who will give us their vision of the contemporary architectural landscape, trying to distance the debate from opinions or superficial perceptions while taking the dialogue to a more reflexive, deep, and fruitful point of view. In this BAQ 2018 Catalog -which aims to enrich the thinking of contemporary architecture- we have gathered essays written by 19 universities and 13 groups of professionals that have carried out 68 critical analysis works on architectural and urban works of the last forty years throughout the world. This publication also incorporates the texts prepared by the invited critics in relation to the conceptual approach of the BAQ, as well as the profiles of the prestigious architects that accompany us in November and who contribute to the Pan-American Architecture Biennial of Quito as the most prestigious architecture event in the American continent." -Pages 20-21 (v.1), In commemoration of 40 years of uninterrupted presence of the Quito Biennial Commission also included an exhibition of the most relevant moments of this important trajectory. Additionally, in its fifth edition, the MIO18 -a project of the Colegio de Arquitectos of Ecuador, Provincial de Pichincha and the Municipality of Quito, through the Instituto Metropolitano de Patrimonio- offered guided tours of the Historic Center.
