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 Den is the sixth stadium that Millwall have occupied since their formation in the Millwall area of the Isle of Dogs in 1885. Previous grounds include Glengall Road (1885–1886), Lord Nelson Ground (1886–1890), The Athletic Grounds (1890–1901), North Greenwich (1901–1910) and The Old Den (1910–1993).
