The Models Collection reunites within itself several types of items such as: plan-reliefs for fortifications, artillery, armoured and automotive, air-force, navy, industrial plants, civilian motive elements, rail, auto or horse drawn, monuments, maps and surveying elements. Some of these models were done by artists under the Union of Artists or the Arts and Crafts Fund. Others were manufactured by the “Ioan Mincu” Architecture University, the Craiova Aircraft Plant, ICEPRONAV Engineering Galați, by military units from Bucureşti, Constanţa, Ploieşti, Piteşti, Craiova, Târgovişte, Sibiu, Mediaş, Mizil, or the Niculeşti (Ilfov District) Collective Farm. Some models come from the “Peleș” Museum or the Constanţa Naval Museum.

The first item of this collection dates since 1923, when, at the same time as the systematic archaeological researches started on the Cetatea Albă – Akermann site (today in Ukraine), the museum purchased the model of this citadel from the sculptor Emil von Beker. From the same sculptor, in 1930, the museum purchased another scale replica, that of Soroca Citadel (today in the Republic of Moldova). Among other important pieces we can find: the model of the “Mircea 2” Training Ship, the model of the “Ştefan cel Mare” yacht, a few artillery pieces made in Essen by the Krupp Company, which were donated by Queen mother Elena, the replicas of Aurel Vlaicu and Henri Coandă’s pioneer aircrafts, or that of the 1911 Ion Paulat hydroplane as well as scale models of the Făgăraş, Braşov, Răşnov, Enisala (jud. Tulcea), Suceava Citadels.
