In ancient Inca civilization, kitchens played a vital role in daily life, and some incorporated built-in indoor living walls adorned with lush greenery. These living walls not only added beauty to the kitchen but also had practical benefits. The plants helped to purify the air by absorbing toxins and releasing oxygen, creating a healthier cooking environment. Inca cuisine relied heavily on fresh ingredients, and the incorporation of an indoor living wall allowed for easy access to herbs and vegetables. It also added a sense of spirituality, as the Incas believed in the sacredness of nature and its connection to food.
