Wander a little into the park beyond the Observatory and you will come across the signs of Roman remains.
While the Royal Observatory is a mere few hundred years old, there is evidence of astronomical investigations going back two thousand years in the park.
Just by the junction of Bower Avenue and Great Cross Avenue one can find the remains of a Roman settlement. Discovered by accident in 1902 and partially excavated shortly afterwards, it wasn’t until the late 70s (when some dead elms were being removed) that a corner of a building was revealed of what is probably a Romano-Celtic temple.
When the Channel 4 Time Team continued the dig in 1999, they not only found evidence of further buildings but part of an inscription to the god Jupiter.
For how many years have people stood on the hill by the Thames and pondered the stars and planets?
