DOLMEN
A dolmen, also known as a portal tomb usually consists of two or more upright stones called Portal Stones supporting a large flat horizontal Capstone.This construction makes a tripod-shaped structure. In Ireland Dolmens date from as far back as 4000 BC. Cremated remains of the dead were placed inside the Dolmens and then covered over with a mound of small stones. This mound is called a Cairn. In most instances the Cairn has weathered away, leaving only the tripod stone structure of the burial mound intact.

COURT CAIRN
Court Cairns are among the oldest Megalithic Tombs in Ireland. Most of these tombs were built in the northern half of the county. A Court Cairn is a tomb consisting of two sections ; a Gallery ( This would originally have been covered) and a Courtyard. The Cremated remains of the dead were placed inside the covered Gallery. It is believed that the open Courtyard was used for ceremonial purposes. The whole Court Cairn would have been covered over by a mound of small stones called a Cairn. In the centuries that have passed the Cairn in all the Court Cairns have since collapsed, leaving the internal stone structure remaining.
In this video watch out for the amount of stones that were used to make the cairn. These stones are now collapsed and lay scattered around the tomb.

NEWGRANGE
Introduction
Newgrange is a Passage Grave – a type of Megalithic ( large stone) Tomb consisting of a narrow passage leading to a chamber where human remains were found. Newgrange the largest megalithic Tomb in Ireland. It stands in the Boyne Valley in Co Meath near two other Passage Graves; Knowth and Dowth. Newgrange was constructed during the Neolitihc Period ( Late Stone Age ) around five thousand years ago ( 3200BC). Newgrange is one of the most impressive stone structures ever built. It is older than the Pyramids in Egypt or Stonehenge in England.
Function
Newgrange was built by the Neolithic ( late Stone Age) people as a Tomb to hold the cremated remains of dead people inside a chamber. Excavations at Newgrange revealed the remains of 5 individuals. This Passage Grave was designed in such a way that for a period of time occurring once a year, around the time of the Winter Solstice – 21st December, the chamber which is normally a very dark place would light up with the dawn sunrise for a period of up to 17 minutes depending on weather conditions. Should the weather be bright and sunny this phenomena can happen at each dawn from 18th to 23rd December. Many believe that Newgrange was built as a form of sun worship. We may never know the exact funtion of Newgrange but we can be sure that these Neolithic people had a respect for their dead and for the sun. These Neolithic builders were very skilled at construction techniques and astronomy and used their skills to bring the winter solstice dawn light to illuminate the remains of their dead.
Structure
The large mound or cairn is approximately 11 meters high and on average 80 meters in diameter. The cairn is made up of thousands of water rolled stones that were collected from the river Boyne. It is estimated that the cairn weighs 200,000 tonnes. The cairn is surrounded at its base by a ring of 97 large boulders called Kerbstones. Surrounding the entire site at Newgrange is a ring of Standing Stones. Several of these stones are now missing.
The passage is long and narrow being 19 meters in length. The passage walls are made up of large stones placed upright – these are called Orthostats. There are 21 orthosats lining the right of the passage and 22 on the left.
Above the entrance to the passage is a rectangular shaped opening called the Roofbox. It is this Roofbox opening that allows the light to shine down the passage on the Winter Solstice. The Roofbox is located high up above the entrance to the passage however the passage floor gradually rises along the 19 meters of its length so that as it enters the chamber the floor has become level in height to the Roofbox. It is this feature that allows the rays the dawn sunlight to travel down the 19 meters of the passage and to reach the chamber deep inside.
The Chamber is quite small but the roof of the chamber is very high- this is called a Corbelled Vault. The roof is built using a technique called corbelling. This involves stacking stones in such a way that they narrow gradually as the rise. A corbelled Vault was needed as it was strong enough to hold up the enormous weight of the cairn which presses down from overhead. The Chamber is cruciform in shape opening out into three recesses or side-chambers. Each side Chamber contains a basin stone which held the cremated remains of the dead.

Construction of the Tomb
Much effort and time was needed for collecting materials for the construction of Newgrange. Remarkably, huge amounts were carried vast distances to the building site at Newgrange. The majority of structural stones in the Boyne Valley tombs are greywacke. This stone type was quarried in the Clogherhead area, north of Drogheda Co Louth. Other granite boulders used in the structure were collected from the North shore of Dundalk Bay. The facade at Newgrange consists of white quartz, which has its origins in the Wicklow Mountains.. The long distances suggest that stone was carried by ship along the sea and the up into the river Boyne whose bank is located one kilometer from Newgrange. . In order to get the stone up the 1km distance uphill from the river Boyne, it is most likely that the Neolithic people used the transportation technique of logrolling. Wooden scaffolding and earthen ramps would have been used to lift and put the stones in place.
Decoration of Newgrange
Negrange is famous for the standard of Neolithic art which is found at the Tomb. A wide range of motifs or symbols are used in Newgrange; circles, spirals, arcs, chevrons and lozenges are among the most common. It has been suggested that these geometric motifs have a symbolic or magical meaning but there is no real evidence of this. Whatever the meaning of these motifs may be they remain as remarkable examples of Neolithic Art in Ireland.
Although carved motifs are to be found both inside the passage and the chamber the best of the carving is reserved for the outside of the tomb on the Kerbstones. The most well known and impressive of these are Kerbstone 1 ( The entrance stone) and Kerbstone 52 ( directly at the back of the tomb). These two kerbstones display an exceptional degree of artistry and craftmanship.
Kerbstone 1 ; The Entrance Stone is 1.3 meters high and 3.2.meters long. Spirals dominate the design which are carved to 1cm depth and 1cm width. A Large Triple Spiral taking up approximately one third of the surface is surrounded by lozenges and smaller spiral designs.
Kerbstone 52 is placed directly at the back of the mound, opposite Kerbstone 1. A large verticle groove is a natural feature of the rock which divides the stone in two. Pockmarks are other natural features on the stone. The artist who designed the carving incorporated the groove and the pockmarks into the overall composition. Spirals and lozenges occur on the left of the design and arcs and oblong shapes dominate the right.
Carving Techniques
The carvings at Newgrange are entirely made using a sharp stone such as Flint. The techniques used are called “Pick Dressing” and ” Incision”. In Pick Dressing the design was picked out bit by bit using a flint and then smoothed over with a pebble. In this way- very deep designs were carved into the stone such as occur on Kerstones 1 and 52. At other parts of the tomb motifs may not be so deep. These more shallow designs have been scratched into the surface of the stone – this technique is called “ Incision”.

BRONZE AGE
Knowledge of metalworking gradually spread from Europe to Ireland during the 2nd millenium BC ( 2000 years Before Christ).The Bronze Age was called so after the metal Bronze which was a mixture of copper and tin. Copper was a soft metal which was easy to shape and mould and it was discovered that if a small amount of tin was added to copper that a much stronger metal was formed. This new metal was called Bronze. During the Bronze Age this new metal was used to make functional objects such as cooking pots, axes and shields. Gold was the preferred metal to make jewellery and decorative ornaments from. Unlike modern times, gold was commonly found in Ireland during the Bronze Age.
Gold Discs
Gold Discs , also called sun Discs were among the very first metal objects made in Ireland. A piece of gold was hammered flat until it became a thin sheet – like gold foil. Then the circular disc shape was cut out using a sharp tool.
The decoration was made using a technique called Repouss é. This was where the design was hammered in from behind so that it stood up in relief in the front. In the Gold Disc from teldavnet the cruciform design was hammered in from behind. The edges of the disc were decorated with concentric circles which were made using the repoussé technique.
It is believed that these Gold Discs were worn – in the hair or attached to clothes. There are two holes in the centre of the discs ( like a button) where gold wire would have been threaded through to tie the discs to the clothes or the hair.
Lunula
Lunula were worn around the neck. They are cresent shaped and are called after the cresent moon – lunula. They were made by hammering gold flat into a sheet and cutting out the cresent shape using a sharp tool. They were decorated with a technique called “Incision”- this involved cutting or incising into the surface using a sharp tool. Typically the designs that were incised into a Lunula were chevrons (zig- zags) and Lozenges ( diamond shapes). Lunula were among the first gold objects to be made in Ireland and they date to the Early Bronze Age.
Torcs
Torcs are twisted bands of gold which were made in various sizes to be worn around the neck, arms,around the waist like a belt or even small ones to be worn as earrings. Torcs date from the middle Bronze Age. They use much more gold than the earlier Bronze Age objects such as the Gold Discs or Lunula and are a much heavier piece of jewellery. . A gold bar or band was twisted to form a rope like pattern. Often the gold bar was beaten thin at the edges to form a flange before being twisted. This is called flange twisting. It produces a much more delicate twisted edge than without flanging.
Dress Fasteners
Dress Fasteners of all sizes were made during the middle Bronze Age. This Fastener below is very large and heavy weighing over one kilo. It probably was used only for ceremonial purposes. It is decorated with engraved concentric circles.
Gorget
A Gorget is a type of gold collar to be worn around the neck. Gorgets were made during the Late Bronze Age and they display the range of artistry metalworking techniques that were developed during the Bronze Age. A Gorget is made in three sections. A collar and two Terminal Discs. The collar is decorated with rope pattern designs using the teacnique of Repoussé which involved hammering in the design from behind so that it stood out in relief. The terminal discs show a range of designs and techniques. In the centre a conical shaped boss stands out very prominently from the surface. Covering the surface of each disc is an elaborate design of rings of dots made in Repoussé and rings of incised concentric circles.
