Only two other London museums saw a drop in visitors in 2000-2001 compared with the previous year: the Sir John Soane Museum in Lincoln's Inn Fields and the National Maritime Museum in Greenwich. The maritime museum's drop may be due to its Neptune court development opening in 1999, which lifted annual attendance figures from 500,000 to 860,000. In that context, last year's 800,000 can be seen as still a huge increase on two years before.
