The North Bank or Northbank Lighthouse, is an active aid to navigation located at the mouth of the River Liffey, near Dublin, Ireland. It is one of four lighthouses that help guide shipping into the Liffey, and the Port of Dublin, all of which are operated and maintained by the Dublin Port Company. Built in 1882, it also affectionately called The Tea Caddy due to its architecture, and has also been described as "resembling a giant mailbox on stilts". Read more on Wikipedia
