How do history and archaeology contribute to the growth of tourism in Ireland?

Ireland has a long history, going back thousands of years. Sites such as Newgrange, which is over 5000 years old are major attractions. History that is a lot closer than that is still very evident. Through Archaeology many remains of earlier times have been found. Dublin's Viking remains have been uncovered down through the years through archaeological digs. Ireland's museums have many artefacts that have been discovered by archaeologists, and more continue to be found. Many of Ireland's historical sites get large amounts of tourists every year, as do their museums.
