The lowland village of Ammos is built at an altitude of 27 metres. It is 14 kilometres from Kalamata and has approximately 140 inhabitants.
The exact date of the village's foundation is unknown, but it is most likely that the area was not inhabited before the Frankish period (13th century) due to the swamps that existed there. In Venetian documents, the village is mentioned under the name Baliaga, after its Turkish commander, the feudal lord Bali Aga. In 1927, the village was renamed Ammos, mainly due to its soil composition, where sand is in excess due to the valley.
The houses of the village are built on the western slope of a ridge, known as "Rachi Kapetaniou" and "Trafos" (probably from an anagram of the ancient word "tafros").
In the village, visitors can see the church of Agios Athanasios, painted by Messenian iconographer Dimitris Giannopoulos. Although the temple celebrates on May 2nd, the annual festival is held in August, so all those living in other regions inside and outside Greece can attend. Also, the old church of Agia Agatha, which celebrates on February 5th, is worth visiting.
