- Cross-cycle Connla's Well / Tobar Segais Connla's Well (Tipra Chonnlai) is the Otherworld well of wisdom in Irish mythology, lying at the mythical source of the Shannon, ringed by nine hazels whose nuts feed its salmon and release the bubbles of poetic inspiration.
- Cross-cycle Croagh Patrick Croagh Patrick is Ireland's foremost pilgrimage mountain, a 764-metre quartzite pyramid above Clew Bay in County Mayo where tradition says St Patrick fasted forty days, and where pilgrims still climb each Reek Sunday.
- Cross-cycle Cruachan / Rathcroghan Rathcroghan, ancient Cruachan, is the royal capital of Connacht: the seat of Medb and Ailill, the opening stage of the Táin Bó Cúailnge, and home of Oweynagat, the cave medieval texts call Ireland's gateway to the Otherworld.
- Cross-cycle Eó Mugna Eó Mugna was one of the five great sacred trees of medieval Irish tradition, a colossal oak in south County Kildare said to bear acorns, apples and hazelnuts together, revealed at the birth of Conn of the Hundred Battles and overthrown by the poets.
- Cross-cycle Eó Rossa Eó Rossa, the Yew of Ross, was one of the five great sacred trees of early Ireland, the famed yew of Leinster at Old Leighlin in County Carlow, praised in a litany of thirty-one poetic epithets and felled, tradition says, by the prayer of Saint Laserian.
- Cross-cycle Tara Tara, the Hill of the Kings in County Meath, is the ritual heart of Irish sovereignty, where high kings were inaugurated, the Lia Fáil was said to cry out beneath the rightful ruler, and the five provinces of Ireland meet.
- Cross-cycle Tír na nÓg Tír na nÓg, the Land of Youth, is the great Irish Otherworld: a realm beyond the western sea, beneath the waves or inside the hollow hills, where time runs differently, no one ages or dies, and abundance never ends.
