Answer the following question: Information: - Dublin is the capital and largest city of Ireland. Dublin is in the province of Leinster on Ireland's east coast, at the mouth of the River Liffey. The city has an urban area population of 1,345,402. The population of the Greater Dublin Area, , was 1,904,806 people. - Drogheda is one of the oldest towns in Ireland, known for its tourism and as a centre of industry, and medical care. It is located in County Louth on the Dublin-Belfast corridor on the east coast of Ireland, 49 km or 30 miles north of Dublin. It is the last bridging point on the River Boyne before it enters the Irish Sea.The UNESCO World Heritage Site of Newgrange is located 8km to west of the town. - The Mary McAleese Boyne Valley Bridge is a cable - stayed bridge in County Meath , Ireland . It spans the Boyne River 3 kilometres ( 1.9 mi ) west of Drogheda on the county boundary between County Meath and County Louth and is part of the M1 Northern Motorway . When it opened in June 2003 , it was the longest cable - stayed bridge in Ireland until 19 October 2009 , when the River Suir Bridge opened on the N25 . Due to environmental concerns , an Environmental Impact Statement ( EIS ) was carried out for the bridge separately from the M1 EIS -- the first such formal EIS carried out and published for a bridge in Ireland . The bridge was built from 2000 to 2003 and was designed by Roughan and O'Donovan , who were awarded the ACEI Presidential Award in 2005 for the design . - The River Boyne (or "Abhainn na Boinne") is a river in Leinster, Ireland, the course of which is about long. It rises at Trinity Well, Newberry Hall, near Carbury, County Kildare, and flows towards the Northeast through County Meath to reach the Irish Sea between Mornington, County Meath and Baltray, County Louth. - Newgrange (or "Bru na Boinne") is a prehistoric monument in County Meath, Ireland, located eight kilometers west of Drogheda on the north side of the River Boyne. It was built during the Neolithic period, around 3200 BC, making it older than Stonehenge and the Egyptian pyramids. The site consists of a large circular mound with an inner stone passageway and chambers. Human bones and possible grave goods or votive offerings were found in these chambers. The mound has a retaining wall at the front, made mostly of white quartz cobblestones, and is ringed by engraved kerbstones. Many of the larger stones of Newgrange are covered in megalithic art. The mound is also ringed by a stone circle. Some of the material that makes up the monument came from as far away as the Mournes and Wicklow Mountains. There is no agreement about what the site was used for, but it is believed that it had religious significance. Its entrance is aligned with the rising sun on the winter solstice, when sunlight shines through a 'roofbox' and floods the inner chamber. Several other passage tombs in Ireland are aligned with solstices and equinoxes, and Cairn G at Carrowkeel has a similar 'roofbox'. Newgrange also shares many similarities with other Neolithic constructions in Western Europe, such as Maeshowe in Orkney, Scotland and Bryn Celli Ddu in Wales. It is the most famous monument within the Neolithic Bru na Boinne complex, alongside the similar passage tomb mounds of Knowth and Dowth, and as such is a part of the Bru na Boinne UNESCO World Heritage Site.
