Southend Pier is a major landmark in Southend-on-Sea, Essex, United Kingdom. Extending 1.33 miles (2.14 km) into the Thames Estuary, it is the longest pleasure pier in the world. The bill to build the new pier, to replace a previous timber jetty, received royal assent as the Southend Pier Act 1829 in May 1829 with construction starting in July 1829. The timber pier was replaced by an iron pier that opened to the public in August 1889. The Southend Pier Railway, opened in the early 1890s, was the first pier railway in the country.
