The old colonial quarter runs west and south of the main praça, a grid of narrow streets where the sobrados stand shoulder to shoulder. These are not the whitewashed, red-roofed houses of the other islands — Fogo's mansions are built from dark basalt, two stories tall, with wrought-iron balconies on the upper floors and heavy wooden doors at street level. Some have been repainted in pastel yellows and blues; others are bare stone, their plaster long since fallen.
Walk slowly and look up. The ironwork on the balconies is often intricate, brought over from Portugal or worked locally by craftsmen whose names have been forgotten. A few houses are protected heritage buildings and have been partially restored; most have not, and you can watch the slow, dignified process of a colonial townscape returning to rock. The quarter is compact enough to cover on foot in thirty minutes, but it deserves longer.
