 Despite the small amount of media usage of the power stations , their four chimneys were still a strong landmark within the south east Northumberland landscape . They could be seen from as far south as 18 kilometres ( 11 mi ) away at Callerton , in Newcastle upon Tyne , and over an 13 @.@ 2 kilometres ( 8 @.@ 2 mi ) stretch of coast , from Seaton Sluice up to Newbiggin @-@ by @-@ the @-@ Sea . This is mostly because the stations were constructed in a largely flat , rural area .
