Today is yesterday's tomorrow's

A hidden gem in the heart of urban Tyneside, Silverlink Biodiversity Park is a fantastic spot at which to enjoy nature in the North East. Created in 1996 on the site of a former rubbish tip, the site was declared a local nature reserve in 2006.

A giant sundial sits on top of the central hill (which I run up for some exercise).

This sundial is inactive without the sun; are you?

Be as true to each other as this dial is to the Sun.
