The first stadiums to be built in the modern era were basic facilities, designed for the single purpose of fitting as many spectators in as possible. With tremendous growth in the popularity of organised sport in the late 1800s, the first such structures were built. Replacing many of the fields and grounds on which early sport played, many professional baseball teams built large stadiums mainly out of wood, with the first such venue being the South End Grounds in Boston, opened in 1871 for the team then known as the Boston Beaneaters (now the Atlanta Braves). However, many of these parks caught fire, and even those that did not burn proved inadequate for a growing game. All of the 19th-century wooden parks were replaced, some after only a few years, and none survive today.
