Watch video ...

From functionality to art

History doorway framing counts thousands of years and is closely linked to the development of architecture and construction technologies. In ancient civilizations – Egypt, Mesopotamia, Greece – door openings were already adorned with carved elements that not only served a decorative function but also had a sacred significance, protecting the dwelling from evil spirits.

In ancient Rome, door casings became an important architectural element reflecting the social status of the house owner. The Romans developed an order system that determined the proportions and decorative elements of casings depending on the importance of the building. It was precisely during this period that elements such as architraves, friezes, and cornices emerged, which are still used in classical door frame.

The Middle Ages brought a new understanding of door framing. In the Romanesque and Gothic periods, doors of cathedrals and castles were framed by complex stone portals featuring religious scenes and symbolism. These portals not only adorned the entrance but also served as a kind of 'Bible for the illiterate,' telling biblical stories through sculptural compositions.
