The building is a 'stepped' structure, and it is on one of these steps that the new green open space has been created through a municipal initiative.

The green roof overlooks the lively local market and has seating and tables. There's also a beehive to celebrate 2012 as the 'Year of the Bee'.

The photo gallery on the Inhabitat website provides an opportunity to review this unusual example of urban architecture and its library spaces.
