by Bolton there is a reservoir, built by Liverpool corporation to give us thirsty city dwellers some water.
Around the lake William Hesketh Lever (of the soap fame) was actually from Bolton, and liked to build stuff (or more accurately pay for people to build stuff). He decided to build a replica of Liverpool castle next to the reservoir.
They where a peculiar lot these philanthropists.
Added bonus factiod: French r?servoir, from r?server, to reserve
