The House of Marriages
The most elegant mansion in Ploiești is popularly known as the Wedding Palace, a name it earned after serving as the city’s registry office. Before that, the property was privately owned by two successive mayors — father and son, both named Radu Stanian — who governed Ploiești around the turn of the 20th-century. At that time, the house was far more modest. Its present grandeur is the result of a major reconstruction in 1926, which introduced elements of the national architectural style so successfully that the building now stands as a textbook example of Romanian architecture.
