Skywatch Friday - Calton Hill
A morning sky striking enough to make me stop for a photo on my long uphill walk to work on Monday. The highest tower with the sort of mast on top is the Nelson Monument, which is visible from ships on the Firth of Forth. From 1852 (tho with a gap of some years due to disrepair), a time ball has dropped from the mast at 1pm Greenwich Mean Time each day, originally as an aid to navigation.
The concertina glass roof on the left of the shot above is Waverley Station, Edinburgh's main railway station. Away in the distance are the Firth of Forth and the hills of East Lothian. One of the lovely things about Edinburgh is that you can see hills and countryside even from the centre of the city.
