Ballachulish
The village of Ballachulish in Lochaber, Highland, Scotland, is centred on previous slate quarries. The name Ballachulish (Ballecheles, 1522-- Straits town,) was a lot more properly put on the location currently called North Ballachulish, to the north of Loch Leven, but was appropriated for the quarry villages at East Laroch and West Laroch, either side of the River Laroch, which were in fact within Glencoe and also South Ballachulish specifically. The primary sector is currently tourist, although many visitors pass promptly by the village itself. The name Ballachulish (from Scottish Gaelic, Baile a' Chaolais) implies "the Village by the Narrows". The tightens concerned is Caolas Mhic Phàdraig - Peter or Patrick's child's tightens, at the mouth of Loch Leven. As there was no road to the head of Loch Leven till 1927, the Ballachulish Ferry, developed in 1733, as well as those at Invercoe/Callert and Caolas na Con were important. The Ballachulish ferry closed in December 1975 when the Ballachulish Bridge finally opened. The Ballachulish Hotel as well as Ballachulish House (until recently a lodge hotel) lie near the tightens at (south) Ballachulish Ferry rather than in the "modern-day" village some 3 miles (5 kilometres) east. Ballachulish House was reputed to be haunted, as well as the drive resulting in it was ridden by a headless horseman. The district of Glenachulish lies in Gleann a' Chaolais, the glen that runs down to the narrows. This is the subject of the Gaelic tune, Gleann Bhaile Chaoil composed by John Cameron (1865-- 1951) and known locally both as the Paisley Bard as well as by his regional label Iain Cealaidh. He is often perplexed with an additional local poet also called John Cameron, known locally as Iain Rob (1822-- 1898). Gleann a' Chaolais is ringed by Beinn a' Bheithir, a massif which consists of 2 munros - Sgorr Dhearg as well as Sgorr Dhonuill. In recent times a variety of new homes have been built in your area along with vacation cabins as well as an art gallery. Additionally the fields of Gleann a' Chaolais have been developed into the 9-hole Dragon's Tooth golf links. Forgeting the tightens is the monument to James of the Glen, "held on this area for a criminal offense of which he was not guilty". Robert Louis Stevenson based his novel Kidnapped around the tale of the Appin Murder. Whoever did eliminate The Red Fox (Campbell of Glenure) is still not known.
