After Pátrai, it is the principal outlet for exports from the Peloponnese, a port of call for small passenger ships, and the seat of the metropolitan bishop of Messenia.

The main market for high-quality olives, currants, and other fruit crops of the Messenian plain, it is served by an airport and has rail links to Pátrai and Athens (Athína).
A Byzantine centre in the 10th century, Kalámai became in 1208, after the Fourth Crusade, a fief of the Villehardouin family, whose castle stands on a hill behind the city. The Venetians first occupied it during the first Turko-Venetian war (1463–79) and again in 1685; in 1770 and in 1821 it was the headquarters for revolutionaries in the Peloponnese. In 1825 it was sacked by Muslims. Kalámai was a major evacuation point for British forces in Greece in 1941. Pop. (2001) city, 53,659; municipality, 70,006; (2011) city, 54,100; municipality, 69,849.
