At present a complex of several buildings and a large courtyard in the Old Town of Vilnius belong to the Library. Most Library departments and Administration are located in the building at Traku Street 10. The Children’s Literature Department occupies a small part of the building at Traku Street 12.

Both buildings are valuable and subject to protection from the architectural aspect. There are many historical documents about them which are estimated by researchers in different ways.

The oldest part of the building at Traku St. 10, near the street, is of the Renaissance style. The façade is classical. The most valuable premises are the hall on the first floor where the General Reading Room now is located.

The building at Traku St. 10 earlier was the palace of the Zenkowicz and Tysckiewicz. The first authentic data about it have been preserved in the Deed of Sale of the 17^th century. However, it is supposed that the house could be built even in the second half of the 16^th century and at the end of the 17^th century it was already restored. In the 18^th century the building was rebuilt, thoroughly repaired and new buildings were attached. It was already called a palace in the archive documents of that time. The house was rebuilt and repaired at a later time, too. In the 19^th century the building belonged to the family of Tysckiewicz.

At the beginning of the 20^th century the most different institutions, shops, offices and dwelling apartments settled in the building.

In May 1951 the present Vilnius County Adomas Mickevicius Public Library was founded in the premises of Vilnius Mass Library No 2 of that time. The institutions and inhabitants who occupied the building little by little were being evicted and the premises were adjusted to a library.

The first project of house reconstruction was worked out in 1971. Unfortunately, it was not implemented. The essential reconstruction of the buildings was started at the end of 1988 but the work was suspended in 1991 and renewed only in 1997.

In 1999 the restoration of the General Reading Room was completed with the help of Lithuanian and Austrian funds. The decoration elements of the end of the 19^th century and the beginning of the 20^th century were preserved (chandeliers, stoves).

At the end of 2001 the Art Department was opened on the second floor where authentic ceiling and wall painting as well as stoves were restored. Aelita Bielinyte is the author of stoves restoration in the Art Department and General Reading Room and of the ceramic works in the reconstructed administration building. 

At the beginning of 2002 the Library Administration and Methodological Department settled in the newly reconstructed premises at the end of the courtyard which were used as outbuildings (ice-house, shed and large stable) in the middle of the 19^th cent.

The house situated by the street at Traku St. 12 now is a building with an eclectic façade of the end of the 19^th century which with almost no changes has preserved until present. The house has interesting and rather rare vaulted arch-shaped windows. The history of the buildings which stood in this place is also very intricate and presented by various researchers in different ways.  

At the beginning of the 20^th century a restaurant as well as a greengrocer’s shop and confectionary were functioning in this house. In 1900-1940 there was an old people’s home here. The building did not suffer during the Second World War. After the war the house was given for apartments and different organizations. In 1977 the Children’s Literature Department was established in the house by the street.

In 2006 the projecting work of Library buildings reconstruction began. The reconstruction work is intended to start in 2007.
