The village of Chomatero is built at an altitude of 66 meters and is 9 km from Koroni and just 2.5 km from the traditional settlement of Mystraki. In ancient times, the village area was under the control of the ancient city of Asini, which later developed to modern Koroni. The written reference to the name Chomatero (Comatero) is made for the first time in the Grimani census, in 1700, by the Venetians. During the Second Venetian Occupation, the settlement was referred to as Gomatero. After the Greek Revolution, families from Alonistaina in Arcadia settled in the village.
The visitor, there, can admire the traditional houses, the building of the old Primary School, and the various churches. The small chapel of Agios Konstantinos is located on the west side of the village. It was built in 1994 by the Miseros family, in their own field, in memory of their father, Konstantinos Miseros. Agia Pelagia's chapel is located at an idyllic landscape with springs and plane trees, on the road that connects Chomatero with the village of Flanthi. The parish church of Agios Dionysios stands out, which was named in honour of the then-mayor, Dionysios Rallis, who contributed decisively to its construction in 1890.
The sights of the village area include the Monastery of Panagia Grivitsiani and the old lignite mine. The discovery of lignite at Chomatero was made, accidentally, at the beginning of the 20th century, during works for the construction of a well. The exploitation of lignite began with the lignite mine in 1916 - 17, while its operation stopped in 1935. In 1940 - 41, the Italians who wanted fuel for the trains reopened the project and in 1944 the Germans came and took it over.
Finally, every year, on August 24th, a festival is held, on the day of the collection of the relics of St. Dionysios. The celebration lasts for two days. The first night is a party with live music and dancing, while the second night is a spiritual-cultural event.
