Dionizas Poška founded in his homestead the first museum of historical antiquities in Lithuania. On the outskirts of Samogitia, in his Manor homestead, he cut down a thousand-year-old oak tree, which was called Baublys, in 1812, truncated it and, having hollowed it out, built an arbour in which he placed all museum antiquities, a library of some 200 books, and made a workplace for himself there; historical and archaeological materials were held in the Baublys.
