The Other Calton Hill Monument

From Wikipedia:
The Nelson Monument is a commemorative tower in honour of Vice Admiral Horatio Nelson, situated on top of Calton Hill, in Edinburgh, Scotland and provides a dramatic termination of the vista along Princes Street from the west. It was built between 1807 and 1815 to commemorate Nelson's victory over the French and Spanish fleets at the Battle of Trafalgar in 1805, and his own death at the same battle.[1] In 1853 a time ball was added, as a time signal to shipping in Leith harbour. The monument was restored in 2009.

The time ball is raised just before 1pm each day, and is lowered at exactly 1pm. I didn't realise that the origins of the 1 o'clock gun are linked to the monument too - the gun was added in 1861 to provide an audible signal to the ships in the Forth on the days when the ball was obscured by fog. Learn something new everyday.

Happy weekend, folks!
