A pub, formally public house (a house "open to the public", as opposed to a private house), is a drinking establishment fundamental to the culture of Britain, Ireland, Australia, Newfoundland, Canada and New Zealand. In many places, especially in villages, a pub can be the focal point of the community. Ireland is an island to the north-west of continental Europe. It is the third-largest island in Europe and the twentieth-largest island on Earth. To its east is the larger island of Great Britain, from which it is separated by the Irish Sea. Irish culture has had a significant influence on other cultures, particularly in the fields of literature and, to a lesser degree, science and education. A strong indigenous culture exists, as expressed for example through Gaelic games, Irish music, and the Irish language, alongside mainstream Western culture, such as contemporary music and drama, and a culture with much in common with Great Britain, as expressed through sports such as soccer, rugby, horse racing, and golf, as well as the English language.
