Since ancient times there was a crossing of the
Dee River at Kincardine O'Neil. Locations of the Dee crossings along with alignment of ancient
trackways formed a major impetus for location of early castles and
settlements. In the vicinity of Kincardine O'Neil the
Middle Ages trackways to the south had a particular influence on development in and around Kincardine O'Neil and Aboyne Castle. Saint
Irchard, a medieval bishop of the Picts, was born in Kincardine O'Neil. In the 19th century, the
Deeside Railway bypassed the village, impeding the expansion of the settlement, unlike towns nearby. By 1895 the population of Kincardine O'Neil exceeded 200. Most of the extant buildings were built in the 19th century. The village was designated a conservation area in 1983 and subsequently granted 'outstanding' status in 1995. ==Amenities==
