The two structures now visible on top of Carn Brea are rather more recent in date; one is Carn Brea Castle, which was first mentioned in 1478 and was partly rebuilt and extended in the 18th, 19th and 20th centuries: https://www.flickr.com/photos/hamishfenton/10176873836 … & http://www.heritagegateway.org.uk/Gateway/Results_Single.aspx?uid=MCO127&resourceID=1020 …
The other structure is the 27m high Basset Monument, erected for Francis Lord de Dunstanville and Basset of Tehidy in 1836–7; it stands on the highest point of the hill, within the enclosed area of the prehistoric hillfort (pic=https://commons.m.wikimedia.org/wiki/File:Carn_Brea_Monument_by_Ansom.jpg …)pic.twitter.com/pbXqdN3ZLP
