A tropical art garden's natural allure

Brazilian millionaire Bernardo Paz has dedicated his life to turning a vast outdoor park of tropical rainforest studded with contemporary art works into one of the most original museums in the world.

Part botanical garden, part gallery, Inhotim is the expression of Paz's unstoppable dream - and of the fortune he amassed in iron ore mining.

But today, while the tycoon's dream is intact, Brazil's economic crisis means his fortune can no longer keep up.
