Before my trip, I saw the above interior photos of José Vasconcelos Library, a huge and modern library in Mexico City. But when I really got there, I was disappointed to find it has been closed for a while. The newly updated wiki page gives the following account -
The Library had to be closed down in March 2007 because of defects of construction. The Superior Auditor of the Federation detected 36 irregularities in its construction and issued 13 motions of responsibility for public servants of the federal government. Among the irregularities found was the misplacement of marble blocks at a cost of 15 million pesos (roughly 1.4 million dollars).
What a shame such a good design didn't get built well and so much money was wasted! I happened to find someone's blog with many pics of this library when it was still in use -
