Passage Tomb on Ringarogy Island
The Passage Tomb on Ringarogy Island ( Irish Rinn Ghearróige ) an island connected to the mainland by a bridge, is located west of Skibbereen in County Cork in Ireland , on a rocky promontory in the mouth of the River Illen, known locally as "The Lag". The island is part of the Carbery's Hundred Isles . Most of the island and the Tomb Passage are flooded at high tide. The megalithic site is of seagrass covered at high tide only are braiding occupied yellow tips of two orthostats to see.
description
The chamber consists of an approximately 3.0 m long and 1.0 m wide north-east-south-west oriented gallery, open to the east, which is formed by three stones in the north and three in the south. A cross-placed stone about 1.1 m high is located with an orthostat 0.5 m high on the north side. The western end of the gallery is closed by an end stone 1.15 m high. Four slabs in the east and two in the south of the entrance area probably represent relocated capstones. The mound was washed away by the tides. About 2.0 m north of the gallery there are three curb stones in situ and three more are on the northwest side. The facility was excavated by Elizabeth Shee Twohig.
In Cork Harbor , the Rostellan Dolmen is an "inter-tidal" portal tomb .
Sea level rise
Some megalithic structures, such as the Allée couverte by Kernic and the Allée couverte in the Estuaire de la Quillimadec in Brittany , are also flooded with high tide today . They are evidence of the rise in sea levels since the Neolithic , when the plants were not built so close to the sea . The menhir of Penloïc (or Penglaouic) near Loctudy (in the Finistère department ) at the mouth of the Pont-l'Abbe river protrudes four meters out of the silt. The menhir, which was built on firm ground in the Neolithic, is about 0.75 m below today's mean sea level, the base is about 0.50 m lower.
