Gun Lane is really only a footpath from the High Road. It's the way I go back home from the Post Office/paper shop when I don't want to walk down the road.It leads to field edge paths and other paths. The gun is reputed to have been bought back from tha Spanish Armada by Trimley's famous son Thomas Cavendish.
It's looking a bit the worse for wear but has stood there as long as I can remember.
