Title: Centre of Scotland
Content:  There have been other centres suggested, such as the furthest point from salt water including sea lochs. The point furthest from the Mean High Water mark is in Glen Quoich, near Braemar, in Aberdeenshire which is 67.6 km from the sea.

Title: Haroldswick
Content:  The bay is located some 615 km north of the closest mainland UK city, Inverness, in Scotland's Highland region and 1,310 km from London. Even Lerwick, the Shetland's capital and only town, is some 96 km to the south. However, Haroldswick's claim to be the northernmost settlement in the UK is surpassed by the tiny hamlet of Norwick-Skaw, situated 8 km to the north. The Methodist Church at Haroldswick is the northernmost church in Britain. For many years, Haroldswick Post Office was the most northerly in the UK and visitors could get a special postmark. Since the office's closure in 1999, this record is now held by the post office in Baltasound.

Title: Coastline of the United Kingdom
Content:  The United Kingdom's coastline is more broken than coastlines of many other countries. It has a fractal or Hausdorff dimension or 'wiggliness' of 1.25, which is comparatively high; the Australian coastline for example has a fractal dimension of 1.13, and that of South Africa is 1.02. As a result of this shape and the number of islands, the coastline of the UK is longer than that of similar sized countries. This means the UK has a relatively high coast/area ratio. Nowhere in the UK is more than 113 km from the coast. It is estimated that around 3 million people (out of 60 million) live on the coast of the UK. The place furthest from the coast is Coton in the Elms in Derbyshire, which is equidistant from Fosdyke Wash in Lincolnshire; White Sands between Neston in Cheshire and Flint, Flintshire in Wales; and Westbury-on-Severn Gloucestershire.

Question: which british city is farthest from the sea?
Answer: Coton in the Elms.
