I am often exercised by lack of structural stability. Often the problem is retaining walls but occasionally a free standing wall gives trouble. couple of years ago such a wall collapsed in Melbourne killing two people (Google melbourne wall collapse for pictures. It was actually a cavity wall which then had a hoarding attached.)
This afternoon I walked to the station in Exeter to collect some tickets. Climbing back up St Clement's Lane, I looked up to see this:
Oh well, Typepad turns it left but I expect you can see.
Looking down from the top it looks like this:
And a last pic to show the wall construction:
Just a half brick wall with occasional full brick piers. Hardly adequate for a 1.5m wall without the addition of a 1m panel cantilevered off the top.
