The Estonian Student Building Brigade collection contains material about the activities of the Estonian Student Building Brigade, a feature of student life in Soviet Estonia. The activities of this organisation are sometimes described as a free space, which is also reflected by this collection. The documents and artefacts show how students used the summer not only for building work but also for provocative entertainment and irritating the authorities. The Estonian Student Building Brigade has a relatively positive image, and is the only remarkable phenomenon from Soviet times which has ever been celebrated since the restoration of independence.
