The view from Lykavettos hill in the centre of Athens is of dull white apartment blocks in every direction. The Greek capital is one of Europe’s most crowded cities, with population densities in some neighbourhoods approaching those of Hong Kong.
Athens has about 2 sq m of green space for each resident, compared with 27 sq m for Amsterdam and 64 sq m for London – and a World Health Organisation recommendation of 50 sq m.
