The crypts beneath Vilnius Cathedral are among the most mysterious and historically significant places in the city. Beneath the main church lie the remains of the earliest sacred structures, dating back to the 13th–14th centuries. Archaeologists have also found traces of an ancient pagan temple, reflecting the period of the old Baltic religion. The underground spaces include chapels, burial vaults, and fragments of the cathedral’s earliest walls, showing how the building evolved over the centuries. One of the most notable sites is the Chapel of Saint Casimir, whose crypt holds the remains of Lithuania’s patron saint. The crypts also contain the tombs of Lithuanian nobles, bishops, and other prominent historical figures.

Among the discoveries is a mysterious sarcophagus found by archaeologists in 1931, still surrounded by legends. The surviving masonry in the crypts reflects Gothic, Renaissance, and Baroque architectural styles. Visitors on guided tours can explore ancient crypts, arched chambers, and restored fragments of burial urns. One area marks the former Royal Chapel, believed to have been the burial place of Lithuanian rulers. The cathedral underwent several reconstructions due to fires, wars, and floods, and these layers are clearly visible underground like a true historical archive.

A small exhibition installed in one of the rooms presents the architectural development of the cathedral. The atmosphere of the crypts is unique—cool air, dim light, and centuries old stone walls create a sense of mystery. Visitors often mention the profound silence and solemnity that fill these spaces. Overall, the crypts reveal not only architectural history but also the story of Vilnius as a political and religious centre. Because of their significance and valuable findings, the crypts are protected and continually studied by archaeologists.
