A glass pavilion is a structure primarily made of glass, designed to create an open and airy space. These buildings often serve as art galleries, event spaces, or private retreats, allowing natural light to flood the interior while providing unobstructed views of the surrounding environment. The use of glass enhances the connection between indoor and outdoor spaces. Glass pavilions can be found in various architectural styles, often featuring minimalist designs that emphasize simplicity and elegance. They are popular in modern architecture, with notable examples including the Barcelona Pavilion designed by Mies van der Rohe and the Glass House by Philip Johnson.
