ヘーラーに対する最大かつ最古の独立した神殿はサモスのヘライオンであるが、ギリシャ本土ではヘーラーは「アルゴスのヘラ」(Hera Argeia)として、旧ミケーネ人の都市国家アルゴスとミケーネの間にある聖域で特に崇拝され<ref>Pausanias, ''Description of Greece'' 3.13.6</ref><ref>Her name appears, with Zeus and Hermes, in a Linear B inscription (Tn 316) at Mycenean Pylos (John Chadwick, ''The Mycenaean World'' [Cambridge University Press] 1976:89).</ref>、ヘライアという彼女を記念した祝祭が祝われるようになった。
Though the greatest and earliest free-standing temple to Hera was the [[Heraion of Samos]], in the Greek mainland Hera was especially worshipped as "Argive Hera" (''Hera Argeia'') at her sanctuary that stood between the former Mycenaean city-states of [[Argos, Peloponnese|Argos]] and [[Mycenae]],<ref>[[Pausanias (geographer)|Pausanias]], ''Description of Greece'' 3.13.6</ref><ref>Her name appears, with Zeus and Hermes, in a [[Linear B]] inscription (Tn 316) at Mycenean [[Pylos]] (John Chadwick, ''The Mycenaean World'' [Cambridge University Press] 1976:89).</ref> where the festivals in her honor called ''[[Heraean Games|Heraia]]'' were celebrated. "The three cities I love best," the ox-eyed Queen of Heaven declares in the ''[[Iliad]]'', book iv, "are Argos, Sparta and Mycenae of the broad streets." There were also temples to Hera in [[Olympia, Greece|Olympia]], [[Ancient Corinth|Corinth]], [[Tiryns]], [[Perachora]] and the sacred island of [[Delos]]. In [[Magna Graecia]], two Doric temples to Hera were constructed at [[Paestum]], about 550 BCE and about 450 BCE. One of them, long called the ''Temple of Poseidon'' was identified in the 1950s as a temple of Hera.<ref>P.C. Sestieri, ''Paestum, the City, the Prehistoric Acropolis in Contrada Gaudo, and the Heraion at the Mouth of the Sele'' (Rome 1960), p. 11, etc. "It is odd that there was no temple dedicated to Poseidon in a city named for him (Paestum was originally called Poseidonia). Perhaps there was one at Sele, the settlement that preceded Paestum," Sarantis Symeonoglou suggested (Symeonoglou, "The Doric Temples of Paestum" ''Journal of Aesthetic Education'', '''19'''.1, Special Issue: Paestum and Classical Culture: Past and Present [Spring 1985:49-66] p. 50.</ref>
In [[Euboea]], the festival of the [[Daedalus|Great Daedala]], sacred to Hera, was celebrated on a sixty-year cycle.
