Exarcheia is a community in central Athens, Greece close to the historical building of the National Technical University of Athens. Exarcheia took its name from a 19th-century businessman named Exarchos who opened a large general store there. Exarcheia is bordered on the east by Kolonaki and is framed by Patission Street, Panepistimiou Street and Alexandras Avenue. Exarcheia is known for being Athens' historical core of radical political and intellectual activism.
