The Alexandru Ioan Cuza Park, also known as the IOR Park, is located in the central-estic part of Bucharest, in the heart of the 3rd district of the city, in an area between the Camil Ressu Street, Liviu Rebreanu Street, Campia Libertatii Street, Baba Novac Street, Constantin Brancoveanu Street and Nicolae Grigorescu Street. Its official name  is given by the statue of the ruler Alexandru Ioan Cuza, placed at the entry near the Baba Novac Street, close to the fountain bearing the same name (Baba Novac).

The IOR Park has a surface of 48 hectares of vegetation to which is added the surface of the lake, reaching a total surface of 85 hectares.

The making of the park started in the 1970s, coming from two directions: one from the Baba Novac Street, named 'Reconstructii' (Reconstructions) and the other one from the Camil Ressu Street and the Nicolae Grigorescu Street, named

'Flax'. The park has a natural lake-The Titan Lake. The lake is divided by the Liviu Rebreanu Bridge in two smaller lakes: the Titan 1 Lake and the Titan 2 Lake. Here exist five islands: the Pensionarilor (the Pensionars) Island, the IOR Island, the Cainilor (the Dogs) Island, the Trandafirilor (the Roses) Island and the Inecatilor (the Drowned) Island. The bigger picture of the park is formed by the green vegetation, the lake and the surrounding neighbourhoods, but it is also defined by the Pogorarea Sfantului Duh (the Descendance of the Holly Spirit) Church, made from wood, in a maramuresean style (Maramures is a northern region of Romania) and it was officialy inaugurated in 1996.

During the last years, the park has been modernised. Now, the park is a green oasis chosen by many people for pleasant walks and outdoor activities.
