The only buildings on Gyaros are the ones that were used when the islet was a place of exile. The imposing prison compound still stands tall on the peninsula between the 4th and 5th cove, along with the hospital, the power station and the scattered outposts. There is a clear view of the cemetery of the political prisoners but it is accessible only through a rough path. Most of the facilities that still exist today were built under forced labor by prisoners or exiles during the first post-war years.
