The Mariampole district is located on the Polish-Lithuanian border and belongs to the Suwałki region. It is an agricultural region in which the Polish minority lives. The capital of the region is Marijampole, in which many 17th and 18th century monuments have been preserved.
Marijampole was founded in the 16th century by Marian priests and their monastery is located here. Blessed Jerzy Matulewicz, bishop of Vilnius, is buried in the classicist monastery church with valuable equipment. The city also has a nineteenth-century neo-Gothic synagogue, an Evangelical church and a small Orthodox church. For Lithuanians, the local junior high school, which was attended by Lithuanian cultural artists from the turn of the 19th and 20th centuries, is of great importance.
Kozłowa Ruda is also eagerly visited by tourists, a town surrounded by dense forests that favor active tourism. The Forest Museum operates here, and the park has been adapted for recreational purposes.
The town of Kalwaria is connected with the Polish Tyszkiewicz family, where in the 17th century bishop Jerzy Tyszkiewicz founded a chapel and stations of the Passion. Today, the most important monument of the village is the classicist church of the Blessed Virgin Mary and the set of buildings of the post station from 1820.
