The historic gardens at Seaforde are situated both within and adjacent to the old walled garden, whose structure dates from the early half of the 18th century. The hidden, micro-climate gardens boast Ireland’s oldest living maze and support a renowned collection of plants, collected from distant corners of the world thanks to the travels of keen plantsman Patrick Forde. The gardens also include an arboretum containing champion trees and rare species. The Tropical Butterfly House is the atmospheric, jungle home to a myriad species of free flying butterflies. All peacefully at home surrounded by exotic and tropical plant life.

One of the best kept Circles I know of. The late Neolithic to earlier Bronze Age monument was excavated in 1937–1939 but its development and date are still not entirely clear. Excavation uncovered a slab feature with three compartments at the west end of the cairn, which could suggest the court tomb tradition, and a single stone cist at the east end which could point to the passage tomb tradition. Cremated remains representing at least seven individuals and some Neolithic pottery were found. Parallels for the outer stone circle with sites in Cumbria have been suggested.
