This is an annual Christmas event and it’s definately worth going to. We went for the first time this year and will probably make it an annual tradition. You visit a lot of the old buildings and at each site you see a vignette of how Christmas may have been there 150 years ago. At the end you stop off at the Lenny Lind for a hot beverage and cookies. My advice if you go is to bundle up nice and warm as it was very cold.
