The Long Gallery is a long, narrow room often found in historic homes and castles, designed for walking and displaying art. It typically features large windows that allow natural light to illuminate the space, enhancing the viewing experience of paintings and sculptures. These galleries were popular in the 17th and 18th centuries, serving as a place for social gatherings and leisurely strolls. Many famous estates, such as Castle Howard and Hampton Court Palace, include Long Galleries, showcasing the architectural style and cultural significance of the period.
