Started in 1906–1907, the reconstruction works were halted during World War I, due to the limitation of resources, but the unfinished building sheltered Romanian and Russian troops, and different public institutions and military hospitals.

[8] Decoratively, the central hall shows a figurative mosaic including various representations of a gothic bestiary, concentrically arranged: two-headed eagles, dragons, griffons, lions.

Besides, some rooms were decorated using a special material licensed by Henri Coandă, under the name of bois-ciment and imitating the oak wood.

The building was also equipped with high-tech facilities for those times, such as electric lighting, (pneumatic) heating, ventilation system, thermostat, vacuum cleaners, which were all directed from the machinery room, at the underground level.

Taking also into account the 14 fires that affected the previous buildings, Berindei (the main architect) treated the wooden structure of the attic with an ignifugeous product called orniton, while for the roof he used a special material, named eternite.

The Moldavia's History Museum was founded in 1916 and offers more than 48,000 objects from various fields: archaeology, numismatics, decorative art, ancient books, documents, etc.

One can admire here the objects used by the inhabitants of Moldavia in their every day activities: in agriculture, viticulture, raising animals, fishing, hunting, apiculture.

It is home to Energetics, Sound Recording and Playback (unique within Romania), Telecommunications, Mineralogy - Cristalography, and Computers sections.

Besides the four museums, The Palace of Culture also houses some other attractions, such as the Gothic Room, which contains a mosaic that presents a medieval bestiarum (gryphons, bicephalous eagles, lions).

There is also the Voivodes' Room, located on first floor, where there are the portraits of Moldavia's rulers and Romania's kings, starting with Decebalus and Trajan, as well as paintings by Ștefan Dimitrescu and his students.

Then there is "Henri Coandă" Room, which was named after the carvings and relief works made by the famous Romanian inventor of a cement invented by him.

In front of the palace there is the equestrian statue of Stephen the Great, framed by two Krupp cannons, trophies from the Romanian War of Independence.
