This paper focuses exclusively on inscriptions on roadside memorials. We conducted a review of studies of roadside memorial inscriptions and a field study of 29 inscriptions found on 156 roadside memorials in Poland to understand the similarities and differences between these inscriptions and those in other countries. The uniqueness of Polish inscriptions is their religious meaning. They reflect the inscription authors' and/or the deceased's relationship with Catholicism. We proposed a typology of inscriptions (limited and developed) that may be useful in further comparative studies on roadside memorialization.
