The Theodor Aman Museum is the first art museum in Bucharest, opened in 1908 in the house where painter Theodor Aman (1831 - 1891), an advocate of modernity in Romanian art, lived for almost 22 years. Built in 1868 - 1869, the house reflects the artist’s vision, from its architectural plans and exterior decorations to the interior design, including stained glass, mural paintings, carved door medallions and panelling. The building maintains its intimate atmosphere, typical of the Belle Époque period, and holds a large part of Theodor's works, covering various genres and techniques.

The collection consists of oil paintings on canvas or wooden panels, engraving plates, pencil and pen drawings, sculptures and all the wood decoration, mural paintings and stained glass. The existing patrimony also includes the artist's work utensils, musical instruments and weapons, oriental and national costumes, ceramic vessels, beads, hookahs and other personal items, which complete the collection of over 1000 museum pieces.
