John o' Groat's House, in Caithness, 1 3/4 mile W. of Duncansbay Head, and 18 miles N. of Wick, was, according to tradition, an octagonal building with eight doors and windows and an eight-sided table within, built by John o' Groat to prevent dissensions as to precedence among the eight different branches of his family. Certain it is that between 1496 and 1525 there was one ' John o' Grot of Duncansbay, baillie to the Earl in those pairts,' and probably a Hollander.
