In ancient Rome, kitchens were designed with a built-in indoor zen rock garden known as a 'viridarium.' These viridariums were an integral part of the kitchen design and were located in the central courtyard of the house. The viridarium consisted of rocks, gravel, and plants, creating a tranquil and serene environment for cooking and food preparation. The kitchen's layout was designed to maximize natural light and ventilation, enhancing the cooking experience. The viridarium in the kitchen served as a place for relaxation and rejuvenation, where the cook could find solace and connect with nature. The ancient Roman kitchen with a built-in indoor zen rock garden was a space where culinary skills and the appreciation of beauty converged.
