Chalazoni is 4.5 km from Filiatra and 11.5 km from Kyparissia. It is built at an altitude of 106 meters and has about 150 permanent residents. According to the Municipality of Trifylia, the village has changed location four times. Its original location was near Agrilos (in the Sotiropoulos estate), but due to the frequent attacks of the pirates, the inhabitants were moved to the east, near Dipotama. This location is called Kato Chorio. Then, for self-protection again, they moved 300 meters further south of the current village to the Paliochori location. Later, the last relocation took place in the area where the village can be today. In the village, the remains of the older settlements, the foundations of Agios Nikolaos, as well as tombs (according to a rough excavation by Georgios Syrekelas) are preserved to this day.
There are several versions of the name of the village. According to the first version, the name comes from the words "good" (kali) and "zone" (zoni), (either because they wanted to express the sense of protection from pirates or to express the feeling of the prosperity of the area), which was altered through time and became "Chalazoni". According to the second version, the name comes from the words "damaged" and "zone" (due to location changes), while the third one argues that the name may have come from the surname of a resident named "Chalazonitis".
In the village, the visitors can enjoy their coffee in the two traditional central square cafes, where the century-old plane tree stands between them. The village's central church is the church of Agios Georgios, while to the north, the renovated church of Sotiros (Agia Sotira) can be found. To the north of the village (in the area of the Desi stream), there are still the remains of the Chalazonian watermills, known as "Chroni’s Watermills". Also, to the south of the village (towards the Skatelos stream) is the old well from where the inhabitants took water until 1885 when the reservoir was built.
Chief Anastasios Papadimitropoulos (known as Captain Anthimos), who was initiated into the “Friendly Society” together with the Filiatrians Karapatas, Skordakis and Panagiotaros, came from Chalazoni. He also took part in the siege of Neokastro, in which his son Mitros was killed.
