Walden is a quiet small town in England. Cars aren't allowed ( 允许 ) into the centre of the town so it's very pleasant to walk around.
Allow at least half a day to visit the museum. It's on a hill just outside the town in a very old building. One room there tells people the history of the building itself.
The museum brings history to life. You can even ride on a horse and cart ( 马车 ) in the street. I was really interested in a 1950s living room in the museum. It was just like my grandmother's house when I was a child.
If you can wait, there's a new exhibition (展览) opening soon. Walden is famous for one thing -- candy! If you like candy, this exhibition is the place for you -- you can learn about its history. I never see so many different kinds of candy. But don't go now because it doesn't start until the 26th of May.
Have a look round the town of Walden too while you are there. If you start in the main square and follow the green signs, they'll take you to the museum, and you'll see lots of other interesting things on the way, too.
