It is always nice to see functional buildings, which are not just built for purpose, but also with their own aesthetic qualities. The pale yellow brickwork and stone show off their intricacies in an understated way, and are set off by a much louder blue sky.
Architectural purists usually like to show buildings with true verticals and horizontals, but I think selecting this detail and taking it from a low angle, with all the accompanying foreshortening and sloping sides adds dynamism and makes for a far more interesting image in this case.
