So much for a remake of 'The Rock', experts say. SFGATE is tracking the Trump Administration’s murmurs for a future modernization of the prison complex at Alcatraz Island, which closed to the public in 1963 and has since become a National Parks Service property that generates an estimated million in tourism revenues each year. On its own, the "plan" itself is hard to estimate or even, for some experts, take seriously, as it could distract from a more subtle push to reopen other federal prison facilities in the area.  The lastestimate had set repair costs at around million. That number amounts to approximately million in today's currency. There is currently an active debate over the reuse of prisons in architecture circles. Ai Weiwei last reused the site ironically as a "celebration of liberty" back in 2014. #logistical #black #hole #blocking #alcatraz039s
