Panigiri of Agia Triada, Chora
20–21 June · Chora (Messaria)
One of the two feasts Kythnos itself names as its most important: Agia Triada in Chora, on the eve and day of Agiou Pnevmatos (Whit Monday). The pattern is the island's classic — vespers, then an all-night glenti with local violin and laouto players and the Kythnian 'balos' dance in the square, continuing after the morning liturgy. Chora is a 10-minute drive from Merichas; the square fills, so come at dusk.
