In ancient Rome, kitchens were an integral part of the household, and some even incorporated built-in indoor living walls with lush greenery. These living walls not only added a touch of natural beauty to the kitchen but also served practical purposes. The plants helped to purify the air by absorbing pollutants and releasing oxygen, creating a healthier environment for cooking and dining. Roman kitchens were known for their innovative designs, and the incorporation of an indoor living wall was just one example of their ingenuity.
