There are many Catholic pilgrimage sites in Lithuania. There is no official list or designation of the sites. The government established the Pilgrim Route of John Paul II (16 sites) in 2007 though there are many more sites that attract local pilgrims. There are many sites visited by residents of the same parish or deanery, or sites that saw their devotion diminish through the years. Priest Robertas Gedvydas Skrinskas in his 1999 guide to pilgrimage sites counted more than 100 Marian images that are considered miraculous and 25 sites of Marian apparitions.[1] As of 2013, there were 33 Lourdes grottoes in Lithuania, mainly in Samogitia.[2] The list below includes only the key sites that continue to be visited by pilgrims.
