A river with distinctive features adds a lot to Dublin. The Lifei River flows slowly through the city centre, dividing the whole city into two parts, north and south, making the old city more quiet and fresh. The River sparkles like a black galaxy, which gives the city a bright light. Dublin is named after the "Black River" which means "Black Pond" in Irish. Ireland is known as the "Peat Kingdom" for its peat export industry. The Irish word for Dublin, the capital, means "black Irish pond". Dublin is located on the eastern coast of Ireland Island, at the mouth of the Liffey River. There are abundant peat resources in the underground of this area. The black Lifei River water can dye the sea water of the Lifei River estuary black.
