The grandson of Alexandros Tombazis recently asked his mother, «Was Grandpa ever young?» That was how Tombazis, for many the most acclaimed modern Greek architect, opened his lecture at the Athens Concert Hall earlier his week. It may seem like an unusual start to a lecture but Tombazis wanted to give an unusual lecture, divided into two parts. In the first, he addressed the «new generation» of architects, many of whom were present. In the second part, he gave a detailed presentation of the Catholic Church of the Holy Trinity in Fatima, Portugal, which is considered of great importance and was inaugurated last October in the presence of 200,000 people. Tombazis conveyed the philosophy behind his career, which spans half a century, in an original way. A pioneer of bioclimatic architecture, he talked a lot about climate change and architects’ responsibilities as well as the era of narcissism and concluded that «there is no architecture without restrictions.» In the part of the presentation on the church, Tombazis pointed out the difficulties brought about by the square in front of the church, which is eerily quiet during the day but abuzz when half a million worshippers show up.
