Devonshire Guest House Doors Open Erin

Devonshire Guest House

This stately guest house sits on part of the original 200 acres (81 hectares) of Crown land that Abraham Nelles claimed in 1820 and sold to Daniel McMillan in 1836. In 1846, Daniel sold half the land to Charles McMillan, who built the house. Now a bed and breakfast, the house has original stained glass, wood trim and hardware.
