The Kalamata International Airport is two kilometers to the east. Since 1892, Messini had a railway station on a branch line from the Corinth-Kalamata railway known as Messinian Suburban Railway. It was closed in 1976, reopened in 2007.Regular operations on the line ceased in 2011 however, until 2016, when it was rendered unusable due to severe weather damage, it operated seasonally from 20 to 28 September for the Messini fair, as well as during the holiday period from 24 December to 10 January.

Province

The province of Messini (Greek: Επαρχία Μεσσήνης) was one of the provinces of the Messenia Prefecture. Its territory corresponded with that of the current municipality Messini (except the municipal units Aipeia, Petalidi and Voufrades) and the municipal units Andania, Meligalas and Oichalia. It was abolished in 2006.

Messini began its communal existence as Nisi, a settlement placed on an island (nēsos, from which Nisi) in the extensive marshland at the mouth of the Pamisos River. It was placed in Frankish territory, the Principality of Achaia, dated 1205-1432, consisting of 40 villages in Messenia and Elis. The ethnic content of the population in the vicinity at that time was Greek. After 1432, when the Byzantine Empire fell and was commandeered by the Ottoman Empire, some Turks entered the region. Except for the names, these distinctions have more or less disappeared in modern Greece.

The government of Greece changed the official name to Messini in 1867. Baedeker's for the later 19th century and early 20th centuries referred to Nisi as "now officially Messini," a phrase that was widely used in travelogues of the period. The earliest Baedeker's to do so is the German edition of 1888. Prior to 1887 Nisi is not treated as Messini. Subsequent references to the place often refer to Nisi as "the popular name".
