Banski dvori were built in the baroque classicism style at the end of the 18th century on the site of the Petar Zrinski's house. Since the properties of the Zrinski family were seized in 1671 after unsuccessful Magnate conspiracy, Petar Zrinski's house on St. Mark's Square was sold to the Čikulini family, later to Count Petar Troilo Sermage and finally Kulmer family. When the old Zrinski house was damaged by fire, Ivan Kulmer renovated it and expanded it to the neighboring buildings. In 1801, he began building a representative palace but ended up selling unfinished project to the Government of the Kingdom of Croatia-Slavonia in 1808 for 75,000 forints. Namely, the Croatian Parliament, who shared the building with the administration of the Zagreb County until 1807, decided to buy a building which would be able to accommodate Parliament, highest courts, and the office of the Croatian Ban, and be used as a storage for the public records and royal books. Consequently, a year later, Ban Ignác Gyulay sold an old parliamentary palace to the Zagreb County which started using it as a town hall, and bought Baron Ferdinand Kulmer's house on the west side of St. Mark's Square. The sales contract was excavated on August 1, 1808. Although there was not enough room for parliamentary sessions in this building, Gyulay's main intention was to ensure that Ban had official residence so the palace was named "Banska palača" and later "Banski dvori" . By the beginning of 1809, the palace was renovated and upgraded so Ban, Royal State Archives, highest courts, and the Croatian Parliament moved in. In 1837, the north complex, the northern wing of the present-day Banski dvori, was purchased from the Rauch family, and after the expansion of the west and north wings, the Ban and the judiciary moved to that part of the palace. On September 10, 1850, during the reign of Ban Josip Jelačić, who lived and died in the palace, the telegraph wire was installed in the palace so Zagreb become connected to the Vienna-based power grid. On April 28, 1850, Deputy Ban Mirko Lentulaj sent the first Croatian telegraph to Ban Jelačić, who was at the time in the official state visit to Vienna. The last major upgrading and expansion of the northwest part of the complex was carried out in 1882, at the end of Ban Ivan Mažuranić's reign. Thereafter, there were no major interventions on Banski dvori which would change the volume and spatial relations of the palace. At the beginning of the Ban Nikola Tomašić's reign, Banski dvori were decorated and renovated. The old reception hall was subdivided and redecorated. In addition, a mirrored ceiling was constructed, mounted old valuable chandeliers installed, the old iron furnace replaced by a ceramic furnace, and portraits of Croatian Ban placed in the great hall.
In 1990, Banski Dvori became the seat of the President and the Government of Croatia. On October 7, 1991, Yugoslav Air Forcebombed Banski dvori with the aim to assassinate Croatian President Franjo Tuđman, President of the Presidency of YugoslaviaStjepan Mesić and President of the Federal Executive Council Ante Marković. None of them were hurt. The presidential residence was immediately moved to the Presidential palace, which was formerly known as Villa Zagorje. The Banski dvori sustained significant damage, but repairs started only in 1995. The building became the seat of the Croatian Government. Between 2001 and 2002, two inner courtyards where fully reconstructed and decorated. Next major renovation occurred in summer of 2008. The whole facade was restored, dormant carpentry replaced, two meeting rooms and the so-called Blue salon renovated, and lobby and sanitary node redecorated. The project was carried out in accordance with the requirements of the Croatian Directorate for the Protection of Cultural Heritage. In summer of 2017, floors with oak parquet and ceiling stuccos and rosette where refurbished. Various carpentry, locksmith and electrical engineering works were also carried out. Air conditioning and ventilation systems were changed as well. In addition, The Ban Jelačić Hall, in which the government sessions are held, has also been thoroughly restored.
