Time balls were important maritime devices for keeping accurate time on ships. Teh balls is raised 5 minutes before noon GMT and falls at noonexatcly . The size and placement must be suitable for viewing from ships.
Stockholm considering itself as a major harbor has one Time ball tower .
It was fully operational from until June 1936, but rebuild again in 1987 .
It is controlled now by long wave time signal from Mainflingen in Germany ( atom clock ) and falls every day at 1 o'clock PM .
Ersta – Sköndal Högskola resides in the building / ( thank you for giving me access to the tower )
1906-1982 it was a building of Stockholms Naval Academy
Time ball tradition is closely inspected by Stockholm City hall and school management gets immediate telephone call if there is some malfunction with the mechanism .
While on the top of the tower I took a hires zoom able image of the view . http://share.gigapan.org/viewGigapan.php?id=26791
