The Den (previously The New Den) is a football stadium in New Cross, south-east London, and the home of Millwall Football Club. The Den is adjacent to the South London railway originating at London Bridge, and a quarter of a mile from the Old Den, which it replaced in 1993. Built on a previous site of housing, a church and the Senegal Fields playgrounds, the Den has an all-seated capacity of 20,146, although that is restricted to approximately 18,100 to allow for visiting fans' segregation and crowd safety measures. The highest match attendance in the 2018–19 season was 17,195.
