When? oaugusta https://padlet.com/oaugusta/greenwich/wish/1480884262 King Charles II. did. The first "foundation stone" was laid on the 10th of August 1675.[1][5]
The place was chosen by Sir Christopher Wren, and since Greenwich Park was already owned by the royalty, no new land was needed to be bought.
One year later, in the summer of 1676, the ROG was completed.[1]

This ball was controlled manually - there was a person, that used to drop the red ball every day at exactly 13:00 (GMT).
Since 1852 the ball has been automatically dropped down by sending an electrical impulse.
Even today the ball is dropped every day at 13:00.
In rare situations, such as when the ball gets stuck due to snow or other unfavourable weather conditions, the ball simply isn't dropped.[1]]]> 2021-05-01 14:53:01 UTC https://padlet.com/oaugusta/greenwich/wish/1480981005
