If you are travelling to Germany don't miss the fist major retrospective of architect Louis Kahn's work on show at the Vitra Design Museum until 11 August. Regarded as one of the great master builders of the twentieth century Louis Kahn created buildings of beauty and powerful universal symbolism. Among his most important works are the Salk Institute in La Jolla, California (pictured), the Kimbell Art Museum in Fort Worth, Texas, and the National Assembly Building in Dhaka, Bangladesh.

The subject of the documentary My Architect directed by the architect's son Nathaniel Khan, this first retrospective on Louis Kahn in over 20 years covers items never seen before including architectural models, original drawings, travel sketches and photographs, as well as unseen film footage. Kahn’s important projects are extensively documented — from his early urban planning concepts and single-family houses to monumental late works such as the Roosevelt Memorial, which was posthumously completed in October last year.

Louis Kahn - The Power of Architecture is presented by the Vitra Design Museum and runs until 11 August, 2013.
