During the past few decades, the practice of architecture has been changed radically. The language of Digital Age generated new styles and types of buildings. One of these buildings is the 'Digital Pavilion'. The pavilion is not only an amorphous thing, adapting to several forms and functions, but is also responsive to changes in its geographical and historical environments. After the obvious impacts of digital technology on architecture, pavilions became non-traditional buildings; their architectural language became images from the future. In the past, pavilions respected the surrounded socio-cultural context to memorize or symbolize a specific event. Now, pavilions appear as space entities coming from the future which totally dislocate from the surrounded context. Applying digitalization made the pavilion's design computational, non-Euclidean geometry, kinetic, dynamic, flow, hypersurface, genetic algorithms, open-ended, unpredictable, and a free three-dimensional structure that giving rise to new architectonic possibilities. This paper aims to recognize this shift happened in pavilions from the traditional shape to the futuristic image. To achieve this aim, the paper will follow a scientific methodology consisting of two parts; first one is theoretical which introduces the meaning of pavilion reviewing its evolution, and then identifies the different design approaches that transform a pavilion to be digital. This part ends by reaching design criteria of digital pavilions. The second part is an application on four case studies which are analyzed then being compared to know the common features used now in designing the digital pavilion. Finally, the paper sets a group of conclusions and the most important is; although the digital pavilion is a small structure but it has a powerful indication to the technological development of the city where the pavilion is.
