A great example of a modern reconstruction of a site, done well. The main feature, the slab cover, is fantastic and once sat down in front of it, studying it's decorated surface, was a real bind to leave. Opening the wooden door and descending into the cairn is quite an experience, too!
Video (quite dark at times) of a visit to Nether Largie North, showing the sliding door on the roof and some detail of the stone lid inside the humid chamber.
