St. Mary Square (Piata Sfânta Maria) is a small triangular square in the Elisabetin district where the 1989 revolution began. The Reformed Church on the southern side of the square was the parish of pastor László Tőkés, whose forced eviction by the Communist authorities triggered the demonstrations that quickly grew into the wider Romanian Revolution.
The square is now a quiet residential plaza with a small Baroque-revival plague column at its centre. A bronze sculpture and several plaques recall the events of December 1989. The square is a short walk south of Victory Square and is best reached by walking down Eugeniu de Savoya Street, one of the city's prettiest Secession-era residential streets.
