Kaišiadorys has been established among four historical capitals of Lithuania, its environs surrounded by the Kaunas sea, the Nemunas and Neris rivers, the main Lithuanian roads intersect here, also the railway construction was of crucial importance for the town to appear, therefore, it is not by chance we can see stylised horses-trains figures shown in the coat of arms of Kaišiadorys.

Laky Žasliai has been known since the Middle Ages, as well as Rumšiškės and Drasūniškis near the Nemunas river, Žiežmariai and Kruonis located at the crossroads, from which most visitors enjoy the Open Air Folk Museum of Lithuania located in Rumšiškės. Visitors can see the farmstead complexes of the ancient Lithuania that reflect the characteristic features of all ethnographic regions.

   The regional municipality is centered in the Town of Kaišiadorys. The territory of the municipality is divided into 11 elderships, namely: Kaišiadorys Town, Kaišiadorys, Kruonis, Nemaitonys, Palomenė, Paparčiai, Pravieniškės, Rumšiškės, Žasliai, Žiežmariai, Žiežmariai settlement.

   Kaišiadorys was first referred to in 1590, but grew into a town after 1860 – when the railway was laid and the railway station was built.

   Žiežmariai was first mentioned in the fourteenth century (1387) in road descriptions of Crusaders. The central part of the town – urban monument, which has retained old features – the network of streets and the market square with densely located houses of craftsmen and merchants.

   Žasliai is admired for its laky and hilly landscape. The dominant of the town’s landscape – Neo-gothic church was built in 1902. A stone with bowls, called the Great, the Altar or Devil’s Throne, located in Laukaglis Village, recalls the pagan times. They say that  the stone is an ancient altar, where people, in pagan times, used to light fire and sacrifice animals.

Paparčiai Dominican monastery was founded in 1649. From Baroque-style brick church and two-storey monastery only a fragment of the gate and chapel have survived. It still attracts visitors and researchers of culture, since it was famous for its rich library, art collections, as well as religious and educational activities.

Kruonis in the time of Grand Duchy of Lithuania belonged to noblemen of the Oginskis family (from 1570 onwards). The present church was built by the Oginskis family in 1610. It has kept their Renaissance bas-relief. Kalviai is small town 7 km south of Kruonis. This town has one of the few circular-shaped sanctuaries in Lithuania – the Church of St. Anthony of Padua (1800-1806), a monumental, classically proportioned local version of 19th cent. neo-classicism, with red granite inlay on the exterior walls, built by the local estate-owners Jozefa and Tomasz Wawrzecki. Its exterior sculptures, Eye of Providence on the triangular pediment, and other details were created by local artisans. The church-yard has several beutiful poleshrines, a wooden belfry, and a wooden sacristy attached to the church building. Today Kruonis is best known for Kruonis pump storage power plant. It is not a coincidence that lightning, a symbol of electricity, has become a motif of Kruonis coat arms approved in 2007.

   The Old Rumšiškės was flooded by the Kaunas Sea in 1958. The old church, the belfry and St Ann’s chapel were moved to the new settlement that was being established upland. Rumšiškės has been famous for litterateurs A. Baranauskas and J. Aistis who used to live here. Those, who wish to admire the beautiful view opening up to the Kaunas Sea and spend a romantic sunny evening, should visit Dovainonys, the high Mergakalnis scar.
