The Pasvalys Hollow Stone Collection consists of more than 50 stones from different areas of Pasvalys district, collected by Antanas Stapulionis. Besides the hollow stones, there is also a large collection of millstones. Exactly in this region the ancient Baltic religion and the gods and goddesses honoured at home remained the longest. Part of stones characteristic of the 15th–16th centuries were later used for other purposes (grating, squeezing, wheel bending, etc.), but their original use at home and for welfare god rituals remains unforgotten.
