St Peter & Paul's is the largest Gothic structure in Lithuania, and the country’s only Gothic church with a basilica floor-plan as opposed to the usual cross-shaped design. Its one-of-a-kind interior, with its nine altars, is also breathtaking. During its history, it was rebuilt several times, which has given the building an eclectic look, with some Renaissance features included.

Krosshaugen is a stone cross dating from the earliest Christian period in Norway (about 1000 AD). This location has functioned as a Parliament site and the cross may be a monument to the farmers who converted to the Christian faith during sessions of Parliament. It is believed that Christian mass was performed beside these stone crosses before churches were built.
