Please give a detailed explanation of the significance of Wemmick's museum in Great expectations? Please explain the following with proper illustrations in about 1000 words.
We have a limit to our answers, so this won't be 1000 words. But Wemmick's castle represents his personal side. In his position with Jaggers, he has to remain cool, harsh, even severe in his personality. As a lawyer's clerk that's the way it has to be. However, Wemmick is a very different man from that persona. So as he makes his way home, he loosens up and becomes a completely open and creative--even eccentric--man at home.
Wemmick lives with is "aged parent" or father who is close to being completely deaf. This alone creates humor because the only way to communicate with him is by vigorously nodding to him (which he finds very pleasing) and shooting off the canon. The fact that he has a canon and shoots it each night is also funny. His home literally "is his castle" although it's a miniature version of one. He has a mote and a drawbridge--all of the items that appear childlike to most adults. This personality shows the reader an alternative to the lifestyle of Jaggers. He is always so serious and harsh. He must be that way for his career. However, Wemmick can offer that type of split-personality where Pip can engage with him and find a true friend.
The use of Wemmick and how he attends to his father is parallel to the relationship Pip eventually has as he aids Magwitch in his last days and how Joe nurses Pip back to health. So the castle is used mostly to develop Wemmick's character.
