The background noise of bustling Berlin ground to a halt when I visited the Holocaust Memorial – a vast museum dedicated to the memory of the huge number of Jews murdered across Europe.  Quietly contemplating the horrors of a period of history the world is still struggling to come to terms with, our sombre mood was elevated by the breathtaking architecture of the memorial itself. Designed by architect Peter Eisenman and engineer Buro Happold, it consists of a 19,000 square metre site covered with 2,711 tall concrete slabs arranged in a grid pattern on a sloping field.  Designed to produce an uneasy, confusing atmosphere, the whole sculpture aims to represent a supposedly ordered system that has lost touch with human reason. Beautiful and sad, the result is a work of art as fitting as it is poignant.
