Aubrey F. G. Bell, Portugal of the Portuguese
“ It is the steep right bank of the Douro which has provided Oporto with its most curious and conservative quarters. There is here little scope for change. The narrow streets descend so sheerly that they have become in places mere flights of stone steps, and the coal smoke of Oporto gives them a coat of blackness. It is the most northern in look of all southern cities. If you were to transport a part of the City or some town of the North of England to the radiant sunshine and crushing heat of Portugal, you might have a like effect. ”
