Founded in 1965, the Lappeenranta Art Museum originally occupied the same space as the Museum of Cultural History of South Karelia, on the northern tip of the Lappeenranta fortress. In the 1980s, the Art Museum moved to the present place in the barracks in the neoclassical style (built in 1798) opposite the Orthodox Church. In 1986, the Art Museum became the Regional Art Museum of Southeast Finland.
The museum houses a collection of Finnish art from the mid-19th century to the present day. The largest single collection of ancient Finnish art in the museum is collected by Viipurin Taiteenystävät ry (Vyborg Friends of Art); this collection includes works by many famous artists such as Albert Edelfelt, Pekka Halonen, Tyko Sallinen, Jalmar Münsterhelm and Eero Jarnefelt. The collection contains paintings by artists who worked in Vyborg or were born there. On the other hand, the collections of contemporary art are focused, in particular, on the art of south-eastern Finland and include paintings by Leena Luostarinen, Unto Ahjotuli, Anna Tompuri, Irmeli Tarmo, Eeva Vesterinen, Heimo Suntio, Sinikki Kurkinen, etc. Д.
Each year, the Art Museum also holds three to four temporary exhibitions, which showcase the latest trends in the art world, as well as works from earlier periods in art history.
Next to the reception is the museum's gift store, which offers a wide range of books, art cards and jewelry.
