Herd Groyne

This is the lighthouse at Herd Groyne.  It stands on the south side of the entrance to the River Tyne on a low seawall built to stop sand from washing into the river and silting it up.  The lighthouse was built in 1882 and as well as marking the position of the groyne it shows navigation lights to guide ships in from the sea.  On course and you see a white light.  Too far to port and you see red.  Too far to starboard and the light is green.  The window which shows the lights can be seen in the third photo but is in shadow.  All photos with iPhone 5.
