architectural styles, Art Deco is notoriously hard to define.
It is highly eclectic and often means different things in different
countries. It embraces a multitude of influences ranging from pseudo
modernist interpretations of cruise liners through eclectic
neo-Egyptian to stuff bordering on Bauhaus, anything other than the
flowery asymmetry of Art Nouveau which preceded it.
Whilst there are
those who say it is merely, as the name implies, a decorative style
without philosophical basis, it was often applied to buildings where
the decorative allusions were deemed relevant, particularly those
with "futuristic" pretentions.
Anyway, this is a
travel site, not an architectural history one, so I am not going to
"do a Pevsner" and attempt to catalogue each and every one, simply
include a few of my favourite examples, adding more as I revisit
digitally or get round to scanning the thousands of slides moulding
away in a cupboard somewhere.
