Less than three days before the opening it is still difficult to be sure Some impressions are clear though and it is not just the panoramic views of Edinburgh Castle that take your breath away Step inside and what immediately hits you is the sequence of spaces Galleries open one into another different sizes different shapes all with pale walls that are wood panelled to look like large blocks of stone and inset with deep display cases Shafts of daylight stream through arrowslit windows and cascade down from the roof lights There is room to ponder and enjoy every item on display
