Skirted by the Northumberland National Park and the North Pennines range, Haltwhistle is ideal for activity and family holidays, walking, cycling, fishing and climbing. Close to where the North & South Tynes meet, with many pretty villages dotted along both river valleys... Early economy Haltwhistle was a market town for the exchange of local goods. In the 18th century two Quakers set up a baize manufactury and there was a weaving establishment. On the Haltwhistle Burn were fulling mills, dyeing and spinning mills. A walk along this stream to the Roman Wall, shows that it must have been a hive of industry with quarries, coal mining and lime burning kilns. The Directory of 1822 (Pigot) gives a whole range of craftsmen, shopkeepers and traders; 60 in number, including makers of clogs. The weekly market was held on Thursdays and there were fairs on 14 May and 22 November for cattle and sheep. Landmarks Hadrian's Wall to the north of the town is used as a major selling point for the town. The section of the wall closest to Haltwhistle is among the most spectacular and complete, with the wall striding eastwards from the lake at Crag Lough along the spine of the Whin Sill. The remains of Haltwhistle Castle and the series of Bastles, and Haltwhistle Tower. Haltwhistle also claims to be at the geographic centre of Britain – equidistant from the sea as measured along the principal points of the compass. A hotel in the centre of Haltwhistle is named the Centre of Britain Hotel in recognition of this claim. The claim is rather tenuous as it requires that the northern extremity is taken to be Orkney rather than Shetland. Depending on how the centre of the island is calculated, however, the centre can be said to be Dunsop Bridge in Lancashire. See centre points of the United Kingdom. A Border reivers' Peel Tower, circa 15th century, is now part of the Centre of Britain hotel and the town contains five Bastle houses (fortified farm houses). Roughly three miles distant from the town centre are Blenkinsop Hall and Blenkinsopp Castle, both Grade II listed buildings.
