Titan (Romanian pronunciation: [tiˈtan]) is a neighborhood of Eastern Bucharest, part of Sector 3. It surrounds the Alexandru Ioan Cuza Park, formerly known as "Titan", "I.O.R." (Intreprinderea Optică Română), and "Balta Albă" (The White Pond).
The name of "Titan" comes from a cement factory located here in the 20th century. Starting with the 1950s, the development stage began. In the context of an acute housing crisis, the Titan was chosen for further city development as there were few constructions on it. Large industrial units were built in the vicinity. Construction lasted until the 1970s, when Alexandru Ioan Cuza Park was also built around the Titan lake.
Titan consists mostly of housing facilities. Alexandru Ioan Cuza park (also known as Titan) is located in the center of the neighborhood. It is one of the biggest parks in Bucharest, with a total surface measuring over 85 hectares. The park is built around the Titan lake, which is divided in half by a road bridge and contains five small islands.
Transportation is well-developed, the region being linked to other parts of Bucharest by subway, tram-lines, trolleys, buses and taxis. The subway stations located in Titan are Nicolae Grigorescu, Titan, Costin Georgian, 1 Decembrie 1918, Nicolae Teclu and Anghel Saligny.
