Monofora

Monofora are windows that have only one opening, like a door for air and light to come in. Imagine your house has many windows, each with a frame and a glass that allows you to see outside. Now, try to picture a window that has a frame, but no glass, just an opening where you can feel the breeze and see outside. That's what monofora is!

In buildings like churches, monasteries, and castles, these windows were used before electricity was invented. They were designed in a way that let natural light come into the building, illuminating it without wasting any energy.

Nowadays, monofora is still used in some places to give a unique and old-fashioned look to homes or buildings. They also serve as great natural ventilation for areas with hot and humid climates.
