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.

The Dolmen can be found on the north east shore of Loughinisland Lake, within sight of Loughinisland Church. A slightly displaced capstone covers a rectangular chamber of which three side stones survive. An early account suggests that this was formerly inside a large circular cairn and approached through a lintelled passage, so it may be the remains of a passage tomb. It is famous as the platform from which Thomas Russell addressed a crowd of United Irishmen in 1803, after the main 1798 rising.
