Fortrose
Fortrose is a town and also former royal burgh in Highland, Scotland, United Kingdom. It is on the Moray Firth, about 6 miles (10 km) north-east of Inverness. The community is understood for its destroyed 13th century cathedral, and as the house of the Brahan Seer. In the Middle Ages it was the seat of the bishopric of Ross, as well as previously called Chanonry, for being the Chanory of Ross. The cathedral was largely knocked down in the mid-seventeenth century by Oliver Cromwell to supply structure materials for a citadel at Inverness. The risen south aisle, with bell-tower, and also a removed chapter house (made use of as the tollbooth of Fortrose after the Reformation) continue to be. These pieces, though small in scale, display substantial building improvement, and remain in the care of Historic Scotland (no entrance cost). The burgh is a prominent area for trying to spot bottlenose dolphins (see Chanonry Point) in the Moray Firth. Fortrose shares a golf links with Rosemarkie. Set on the Chanonry Ness the training course stretches out into the Moray Firth and offers great views of Ft George. The training course is popular for its signature 4th Hole "Lighthouse". The lighthouse in question is the Chanonry Point lighthouse which was designed by Alan Stevenson and was first lit 15 Might 1846. Public structures in Fortrose consist of a recreation centre, library and also the only high school on the Black Isle, Fortrose Academy. The appropriate pronunciation of the town's name according to regional use is with the tension on the first syllable.
