The Royal Observatory was built in 1675 by order of King Charles II and designed by Sir Christopher Wren The main building is Flamsteed House named after John Flamsteed the astronomer royal of the time. Its principal function was the establishment of longitude and astronomical observation. The red ball on one of the towers was the first public time signal. At five minutes to one every day it rises half way up the pole reaching the top at two minutes to one. It drops at exactly one o' clock and since it can be seen from a great distance and particularly from the river, it was and is used by mariners leaving Thames ports to set their timepieces. From the clues in the photograph you can easily deduce that this is a sunset picture.
