In honor of the fiftieth anniversary of Louis Kahn’s death, in March 1974, this facsimile edition presents the notebook in which the famous American architect sketched and wrote during his travels in the last year of his life.

The centerpiece of the notebook is a series of magnificent drawings that illustrate Kahn’s design process for the Franklin D. Roosevelt Four Freedoms Park in New York City (1973/74, completed posthumously in 2012). The booklet offers an in-depth look into the architect’s mind; the personal sketches and poetic reflections reveal Kahn’s spiritual understanding of architecture as part of our overall environment and shed new light on his influential philosophy surrounding design, construction, and conception in architecture.
