Dominican Church of the Holy Spirit

Its height with the cupola is 51 m. The bottom part of the façade (with small twin towers) is covered over by monastery buildings.

It is heralded by the cartouches of the portal with coats of arms and fresco settings in the monastery-like corridor leading to the church.

The church also has many Baroque frescoes; a multi-figural composition "Apotheosis of the Holy Spirit" (neo-Baroque, 19th century) in the cupola.

45 paintings in the church (an image of St. Barbara with a 17th- or 18th-century setting, a rococo "St. Catherine of Siena" by Szymon Czechowicz, a portrait of Alexander Jagiellon by an unknown artist of the second half of the 18th century) are considered monuments of art.

The dungeons house remains of hundreds of Vilnius residents, some of them naturally mummified, and are surrounded by urban legends.

More romantic are claims that these dungeons were once part of a larger tunnel network that allowed legendary lovers Barbara Radziwiłł and Sigismund II Augustus to meet in secret.

In 2011, anthropologists from Vilnius University, led by Rimantas Jankauskas [lt], began a study of the mummified bodies.
