Lisnagade is a large multivallate earthen ringfort, three miles west of Banbridge. It is an impressive circular earthwork, consisting of three massive ditch-separated banks, approximately 6m high, which completely surround the fort. The diameter of the inner circle is a good 60m and the total diameter of the rath is about 110m. There is a smaller rath annexed to the north by two straight ditches. This rath is very low and is about 30m diameter. It is surrounded by a single ditch.
Though bronze artefacts have been recovered from the site, little is known about its occupants. This ancient site dates back more than 1000 years, and is thought to have been constructed around 350 AD. The interior has now only low undergrowth and a beech tree just off centre. The banks are planted with a variety of well established trees as well as small bushes.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
