Palanga Amber Museum is the unit of the Lithuanian National Museum of Art which each year receives the largest numbers of visitors.

The Museum was established in the mansion built in 1897 by Count Feliksas Tiškevičius and his wife Antanina Korzbok-Łącka. The mansion was designed by the famous German architect Franz Schwechten. The mansion stands in the most beautiful location in Palanga: a park designed by the French landscape architect Édouard François André. After World War II, the Artists Creative Work and Leisure Home made its home in the mansion. On 3 August 1963, the first exhibition space of the Palanga Amber Museum was opened in two halls of the mansion. The Museum’s opening marked an important event in Lithuanian cultural life. The first exhibition space quickly became a significant centre for amber collection, research and promotion as well as one of the most visited museums in Lithuania. Currently, the Museum’s collections include over 30,000 exhibits, 5,000 of which are displayed to visitors in a permanent exhibition. The exhibition is improved, expanded and supplemented with newly-acquired exhibits each year.

The exhibition presents two main topics: the creation of amber during the evolution of Earth and the usage of amber in the history of culture. Each topic is divided into several sub-topics. Visitors have an opportunity to get acquainted with the most important information during a guided tour.

Museum of the Radvilas Palace is a subdivision of Lithuanian National Museum of Art. In the middle of the 17^th century, the Radvilas Palace was one of the most beautiful in Vilnius. 17^th–18^th  centuries wars and fires devastated them. At the beginning of the 19^th century, the then owner of the palace, Dominykas Radvila (1786–1813), transferred the abandoned, uninhabited palace to the Vilnius Charity Society, which operated here until 1940. Under the possession of charities, the dilapidated palace buildings were demolished or fundamentally rebuilt. In 1967, restoration work has begun at the Radvilas Palace. 

In 1990, a subdivision of the Lithuanian Museum of Art was established in the restored part of the Radvilas Palace. One hall of the palace was dedicated to the Radvilas and named the Radvilas Hall. It provides an insight into the famous Radvila family and its most prominent representatives.

In 1996, 12 exhibition halls have already been installed in the palace. In 2002, the area for exhibitions has expanded, and it has become possible to organize more cultural events in this palace.

The museum was founded in 1987, and is housed in the reconstructed building of the Old Arsenal of the Lower Castle of Vilnius Fortress. This palace was built at the beginning of the 17^th century, on the remains of wooden buildings, floorings and defensive walls of the Lower Castle of the 12^th– 14^th centuries. 

The fires raging in Vilnius in 1654, when the war with Russia began, and also in the 17^th century, when Lithuania passed through a series of wars, significantly damaged the palace. In 1807, Dominykas Radvila (1786–1813) handed over this palace, which by that time was already in very poor condition, to the Vilnius charity, in whose jurisdiction it was until 1940.

In 1967, the reconstruction and restoration of the Arsenal and its adaptation to the museum’s needs began. During the restoration, the spatial structure of the late Gothic architecture of the 16th century, as well as the Renaissance facades of the early 17^th century, were recreated.

In 1987, the Museum of Applied Arts was established in the old arsenal. In 2016, it was renamed the Museum of Applied Arts and Design.
