The Seaton High Light was built in 1839 and originally stood 1 mile inland as it was used in conjunction with the Seaton Low Light to mark a shipping channel.
It was relocated to the Marina in 1995, eleven black marble plaques bearing the names of those lost at sea now surround the column.
Originally a paper mill from 1757, it was converted to produce linen for sails in the 1850s. It was closed in 1908 due to the decline of sailing ships 
The mill was demolished in 1937 to widen the road, but there are the remain of a sturdy sandstone wall on the riverbank which was presumably part of the building.
Sir William Gray was the first Mayor of West Hartlepool from 1887 to 1888 and founder of the shipbuilders William Gray and Company 
This status was unveiled on 26th March 1898 by Alderman Clarkson (or rather the wind which blew off the covers before he had chance), the sculptor was William Day Keyworth Jr with the foundry being Rovini and Partanti
The name of Hartlepool is supposedly derived from Heruteu, ‘Island of the Stag’ via Hertepol, ‘Pool of the Hart’
The tale of the residents of Hartlepool hanging a monkey as French spy during the Napoleonic Wars is very well known.
This Make A Wish For The Monkey statue in the marina, now collect coins for charity.
The site known as Greatham Saltworks was founded in the late 1800s before becoming Cerebos around the turn of the century. In 1968 Cerebos became part of Ranks Hovis McDougall and products such as Bisto Gravy and Atora Suet were manufactured.
From 1997 to closure in 2002 some Sharwoods products were made here, on the day I visited it was in the final stages of demolition.
The internals of site were photographed extensively on urbex sites such as 28 Days Later
Another part of the extensive network of wartime defences around Greatham.
As with the example next to the football field, all the loopholes are covered with modern bars, despite the door still being wide open.
I previously posted about this location in early 2009
Since that time much of the undergrowth has been cleared by the Friends of Errington Woods, allowing a much better view of the hauling engine bases.
Some of the ubiquitous Pease bricks can again be found, but this time in their more normal cream.
This large brick base was the base for a steam engine which drove a Waddle Fan used to ventilate the mine, and the hub of the fan itself.
Some foundations of the building built in 1903 can also be seen now the area has been cleared by the Friends of Errington Woods
Many of bricks lying around this area have the impression of Pease and Partners, the mine owners.
The Mechanics Institution was built in 1854 and is listed as being designed by James Pigott Pritchett, although it may be the work of his son James Pigott Pritchett Jr who set up a practice in Darlington in that very same year.
In later years its been a bank and a bar.
