Istanbul’s Gecekondu Homes Reveal the Building Blocks of a Megalopolis

Gecekondu, or “landed overnight,” homes were hastily constructed as residents from the countryside rushed to Turkey’s urban centers after World War II.

In the shadow of Istanbul’s better-known buildings — its historic Ottoman mosques, its grand late-19th-century apartments, its modern skyscrapers — the wanderer occasionally stumbles upon a structure that looks out of place even in a city famous for its mélange of architectural styles and eras. These small, squat, simple homes, often with roughly white-washed walls, a metal door, and a low-pitched roof, are more redolent of the hardscrabble countryside than a megalopolis of more than 15 million people. But though few of these homes, referred to as gecekondu, (“pronounced “GEDJ-Eh-Kond-U” — the first syllable rhyming with “hedge”) remain standing in this form, these humble abodes are vital to understanding how Turkey’s largest city became what it is today.
