What is when were hallways invented?

Hallways have been around in some form since ancient times, but they were not considered a specific architectural feature until the Middle Ages in Europe. Prior to this, homes and buildings were designed with large open spaces with rooms and chambers off of them. The first recorded use of the term "hallway" dates back to the 17th century. As buildings became taller and more complex, hallways became more important for connecting different parts of a building and providing access to rooms and spaces. The invention of electricity and indoor plumbing in the 19th century also contributed to the growth and importance of hallways in modern buildings. Today, hallways have become a ubiquitous feature in homes and buildings around the world, serving as both functional and decorative spaces.
