An important element of Ottoman architecture in Turkey was the addition of birdhouses affixed to the outer walls of significant city structures, a safe space for regular avian guests to nest outside of mosques, inns, bridges, libraries, schools, and fountains. In addition to providing shelter, the birdhouses fulfilled a religious vision. They were thought to grant good deeds to those that built the tiny homes. Through their abundance and care, the structures encouraged a love of animals in the Turkish public, citizens who adopted several nicknames for the homes over the years including “kuş köşkü” (bird pavilions), “güvercinlik” (dovecots) and “serçe saray” (sparrow palace).
