Oldcastle

The largest collection of megalithic graves in Ireland, with 30 passage tombs from around 3300 BC, older than Newgrange. They're ranged across four small hills together known as Slieve na Calliagh, "the witch's hills", and the hill you visit is Carnbane East (194 m). Its largest tomb is Cairn T, 35 m in diameter with Neolithic artwork: the sunrise at spring and autumn equinox penetrates its depths. Entry within is by guided tour. (In early 2021 this tomb is closed for conservation, others remain accessible.) "The Hag's Chair" nearby is a large carved kerbstone. The area is steep and rocky, wear stout shoes.

Charming gardens with many original 17th century features. The house is now an event venue and can't routinely be visited. It's burnt down three times, with only outbuildings surviving, especially the Orangery. This has been converted into plush self-catering, sleeps 17. The Plunkett family backed the breakaway Irish Confederacy in the 1640s, so their lands were forfeited to the loyal Napers, who still own it. The Napers restored the gardens; they also staged an annual opera festival here but this is no longer held.
