Passage 2.34.10
ἐνταῦθα ἡ προτέρα πόλις τοῖς Ἑρμιονεῦσιν ἦν. ἔστι δέ σφισι καὶ νῦν ἔτι ἱερὰ αὐτόθι, Ποσειδῶνος μὲν ἐπὶ τῆς ἀκτῆς τῇ ἀρχῇ, προελθοῦσι δὲ ἀπὸ θαλάσσης ἐς τὰ μετέωρα ναὸς Ἀθηνᾶς, παρὰ δὲ αὐτῷ σταδίου θεμέλια· ἐν δὲ αὐτῷ τοὺς Τυνδάρεω παῖδας ἀγωνίσασθαι λέγουσιν. ἔστι δὲ καὶ ἕτερον οὐ μέγα τῆς Ἀθηνᾶς ἱερόν, ὁ δὲ ὄροφος κατερρύηκεν αὐτῷ. καὶ Ἡλίῳ ναὸς καὶ ἄλλος Χάρισιν, ὁ δὲ Σαράπιδι ᾠκοδόμηται καὶ Ἴσιδι· καὶ περίβολοι μεγάλων λίθων λογάδων εἰσίν, ἐντὸς δὲ αὐτῶν ἱερὰ δρῶσιν ἀπόρρητα Δήμητρι.
Here the Hermionians had their former city. Even now there still remain sacred places there: at the very beginning, a sanctuary of Poseidon situated beside the shore; and farther on from the sea, ascending into the higher ground, a temple of Athena. Beside this temple are the foundations of a stadium, and they say that the sons of Tyndareus competed in that place. There is also another sanctuary of Athena, smaller, whose roof has collapsed; as well as a temple to Helios and another to the Graces. There is also one temple built for Sarapis and Isis; moreover, enclosures composed of large, selected stones exist, within which the Hermionians perform secret rites in honor of Demeter.
