Curious about windows and their relation to the regions around the world that they reflect, photographer Andre Vincente Goncalves set out photographing thousands over several years, and compiled them into the whimsical series ‘Windows of the World.’ The result is a mesmerizing study of the evolution of the window itself, from the early iterations that were simply a hole in the wall.

“When I’m photographing, I give a lot of importance to the small details,” Goncalves tells In Sight. “Everything about them fascinates me, the patterns, colors. … I find it amusing that a small piece of glass between the interior and exterior of a house gives us the feeling of security. Some are very flashy and opulent and others very humble.”

In the process of choosing the photos of the windows, Gonclaves normally eschews the most beautiful ones in favor of using photos that relay a particular identifying factor about the city or region. In Lisbon, for example, he chose the windows with tiles because the tile is a symbol of the city’s cultural heritage that dates back to the 16th century. In Evora, another Portugese city, Goncalves picked the windows with white walls and the details in yellow. The houses are white is because during the summer, the city becomes incredibly hot, with temperatures over 107 degrees Fahrenheit (42 degrees Celsius).
