Historical population Characteristics In the 19th century, the Imperial Austrian surveyors were sent to re-measure the area and to set the future look of the village. They measured and marked the main and side streets, divided the area in the lots for housing, yards, churches and other public buildings. They arranged the crossings of streets at the right angles so the village consists of the proper blocks which contain 12 houses each. Hence, Selenča is a typical settlement of the Pannonian type, compact, square shaped, with the regular grid-like layout of the streets. However, as the village grew, generally in the southwest-northeast direction, the non-planned building and expansion produced irregular street patterns on the periphery. With this expansion, old core of the village was connected to the neighboring salašes. Total area of the village is By the 2000s, there were still surviving the old, original houses, made from the wattle daubed with mud, with wooden roofs covered with reed. The streets in the village are paved with the asphalt concrete while the sidewalks were made of concrete or bricks. Considered a prosperous settlement, by the 2000, Selenča had a kindergarten, a modern community health center, cultural center, founded in 1948, with large library and a cinema, Slovak cultural-artistic society "Jan Kolar", also founded in 1948, with drama, music and dance sections and a hunters association.
