An original manor house dates from 1662 and existed prior to the current one, and was described by Jonathan Couch in his History of Polperro (1871): "At the top of the eastern hill ... is the neat old manor-house of Killigarth, with its antique square-headed and granite-mullioned windows, its respectable arched doorways, and massive chimneys ...

It is also possible that part of the house was simply remodelled, rather than fully demolished as the 1662 date stone remains.

[2] Presently the grounds include a John Fowler Holiday Parks site, with some guests staying in the manor itself.

[3] Killigarth was probably owned by John de Kylgat, who is listed by Richard Carew as being among those who had estates of £20 a year in the reign of Edward I.

[4] Sir William Beville and his wife Frances Knyvet lived here in the reign of Queen Elizabeth I.
