Espace Alcatraz was one of the Hide and Seek maps on Minecraft Central. It was released 1st October 2013 and the creator of the map is unknown. It was removed when Hide and Seek was removed, 19th March 2015.
The map was based on a prison. It had a yard surrounding the prison building and inside the building there were multiple prisoner cells. Access inside the building was later blocked and the hiding area was limited to the yard. The blocks you could hide as have not been recorded.
