Museum Oscar Niemeyer
In 2002, the building that had been used for the state departments was remodelled and transformed into a museum. A new annex was constructed based on the silhouette of an Araucaria tree, typical of the Parana State flora. However, it is popularly known as the "eye". A tunnel in the basement connects the two buildings. Oscar Niemeyer created the entire project, and in tribute, the Parana Government named the museum after him.
