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.

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.

Ringhaddy Sound is located on the western shore of Strangford Lough to the west of Islandmore. With its unusual swollen hills it is a real joy to cycle. Descend into the sound, and enjoy the atmosphere. A Castle ruin and Church sit further on the Peninsula, but alas they are on private land. It is possible to arrange access from the land owner however. There is also a Beautiful mooring with a Boat Club that has full facilities if needed. Heres a bit about the Castle. This is one of the most completely surviving tower houses in the county, retaining its gables and formerly an original wooden window. There were at least two main phases of construction at this site. The ground floor, which had a stone vault, dates from the 15th century, while the upper parts were rebuilt in about 1600. It is rectangular in plan with small turrets at the north-east and south-west angles, one with the stair and the other with a latrine chute. There are large fireplaces on the first and second floors, and an attic in the roof. A distinctive stone rainwater spout projects from the east side. The castle seems to have changed hands between Bryan McArt and the English in the early 16th century, and it is likely that the earlier castle was McArt’s stronghold, slighted when he withdrew, and rebuilt by the new English owner. Underwater investigation has confirmed the presence of a stone slipway beside the castle, and water transport was clearly of great importance in this location.
