The Sagrada Familia in Barcelona, its nave completed since my first visit 22 years ago, conveys the excitement the first gothic cathedrals must have evoked when they were built: structures so tall and light-filled that the only analog was not other work of human hands but a forest. (I note with satisfaction also that Gaudí's treelike columns look pollarded!) If you resist the symmetry, the skylight-spangled ceiling's forest-like too!
