Until the end of the 19th century it was the residence of the rich family Rosetti-Roznovanu. The entire Russian diplomacy, from the Organic Regulation period (1829-1831) used to work here. On the 3rd of April 1866, in the palace yard, a violent separatist manifestation took place. The news of Prince Alexandru Ioan Cuza’s abdication and bringing to the throne of a foreign prince reactivated the Anti-Unionist Movement, formed of Moldavian boyars unsatisfied by the situation of the Principality of Moldavia after the Union. The objective was the separation from Wallachia and bringing to the throne the boyar Neculai Rosetti-Roznovanu. The army intervened at the order of Lascăr Catargiu and after some violent street confrontations, the anti-unionist barricade, from in front of Roznovanu Palace was taken down, with victims on both sides, and the leader were arrested. On the rebellion, Ion Creangă also participated for the anti-unionists, saving Moldavia’s metropolitan who was wounded in the confrontations.
The palace hosted important figures of the epoch, members of the royal houses, but also famous artists, such as Hariclea Darclée and George Enescu. In 1891, mayor Vasile Pogor got the building from the Roznovanu family. There is also a legend saying that the palace had been lost at a card game by the owner. The construction was modified in order to the be used as headquarters of City Hall. Since 1893 it was designated as a royal palace, but during the refuge in Iași in the First World War, the royal family preferred other buildings. An important figure for those hard times was mayor George Gh. Mârzescu (1914-1916), because he took firm measures for the hosting of refugees and the population’s provisioning. The Archives and the Justice Court were hosted then in the building. In 1944, it became the Residence of the Party City Committee and in 1970 it became once again residence of the City Hall.
The eclectic decorative elements were placed after the decision of transforming the building into a royal palace. On the upper side, there are specific elements of the French Neogothic (rich Romantic heraldry, trapezoidal shaped roof) and in the inside, there are mainly Baroque adornments, today much more simplified due to renovations. At the entrance, visitors are welcomed by the monumental stairways which lead to the hallway guarded by marble Corinthian columns. The big meetings and parties from the past held in Vasile Pogor Hall were replaced with the Local Council meetings, guarded by the portraits of the mayors of Iași. The City Hall guide can tell tens of stories which marked this majestic palace.
