Imperial War Museum

The Imperial War Museum (帝国戦争博物館 ていこくせんそうはくぶつかん ,) is a British nasional museum located in London. It's the place where Iscariot's leader, Enrico Maxwell met Sir Integra, Hellsing's headmaster. It's a minor place that appears in only one chapter of Hellsing, and never mentioned or seen again.

About
In real life, the "Imperial War Museum" is actually an organisation with five branches located in England, three of which are specifically in London, and was founded in 1917. The museum was intended to record the civil and military war effort and sacrifice of Britain and its Empire during the First World War. It was originally opened in 1920 with a location housed in the Crystal Palace located at Sydenham Hill.

Simply, it's a historic museum. Typical stuff includes a historic painting drawn by someone way back before the 90's and for all we know, it's a huge museum full of paintings and sculputures and as such, intriguing; even Anderson was quite fond of the museum; wanting Enrico Maxwell to sometime, bring the orphans from Ferdinant Lukes to come over. All the paintings included within the notable hallway that Sir Integra and Enrico Maxwell met in, is protected by fences that's connected with each other, that goes on pretty long. It's also said that this is a pretty popular historic museum based in London.

It's also mentioned to have a cafeteria outside, and was later used by Integra and Maxwell to actually talk peacefully, without any interference by both respective Trump Cards. While both leaders were talking, The Major along with the Doctor was present, and watching them from behind, so it appears that this cafeteria is quite big compared to others.
