The wall was part of the original ballpark construction of 1912, along Fenway 's north side facing Lansdowne Street. It is made of wood and was covered in tin and concrete in 1934. It was then covered with hard plastic in 1976. A manual scoreboard is set into the wall, which has been there, in one form or another, at least as far back as 1914 (see photo at right). Despite the name, the Green Monster was not painted green until 1947; before that, it was covered with advertisements. The Monster designation is relatively new. For most of its history it was simply called "The Wall. ''
