Or else, the element may be Pictish and derivation from a word related to Welsh bron, "breast, breast-shaped hill", has been suggested by linguist Guto Rhys.

[1][2] Atop the hill is Kinpurnie Tower, designed by Rev Alexander Bryce (1713 - 1786), minister of Kirknewton and later East Calder and built by amateur astronomer James Stuart-Mackenzie in 1766 to be used as an observatory.

It stands next to the site of an unfinished iron-age fort; remains of the vitrified walls and the large ditch can be seen in the area of the viewfinder and trig point.

The tower, which has walls 1 metre (3.3 ft) thick, fell into serious disrepair after it ceased to function as an observatory and faced demolition in the early 1970s.

However, as it was such a well known landmark, plans were drawn up to restore the structure and the work, funded by the local authority and the Cayzer Estate, was completed in 1974. https://www.walkhighlands.co.uk/angus/kinpurney-hill.shtml http://www.walkscotland.com/route119.htm
