Dead end.

Opened in 1998, the Museum of Scotland building houses collections relating to Scottish antiquities, culture and history. I like the building but it is not unknown for me people to get lost in it for hours before accidentally finding their way back to civilisation. Here is an example of one of the lost visitors finding himself with nowhere to go.
What the building also has going for it is that Prince Charles apparently resigned as patron of the museum, in protest at the lack of consultation over its design. Just think how confusing it might have been had he stayed on.
