Piața Unirii

Piața Unirii (Romanian pronunciation: [ˈpjat͡sa uˈnirij], Union Square) is the largest square in central Bucharest, Romania, and one of the largest public spaces in Europe, being located in the center of the capital where Sectors 1, 2, 3, and 4 meet.

The square is a significant transportation hub, containing the Piața Unirii metro station and a major interchange for STB buses; there is also a tram terminal near the southwest corner.

There were plans since the interwar period to build the Romanian National Salvation Cathedral on the place of this park, but in the early 2000s the idea proved technically impossible due to the busy underground environment and therefore the location was changed.

In 2023, an analysis carried out by civil engineers revealed severe degradation to the cover of the Dâmbovița River at Piața Unirii.

The cover, which was part of a larger, unrealized project between 1938 and 1941, was found to be in a state of advanced degradation, with exposed rebar and crumbling concrete.
