Architecture, archaeology and continuing use

The stone head offers several incised dial planes at different angles above a plain square support. Carved symbols and the initials “RR” connect practical solar measurement with the identity and status of the Reay household.

Its story

Installed during the Mackay occupation of Tongue House, the sundial predates the major 1750 expansion. Later landscape remodelling retained it as a focal object on the principal garden terrace.

Why it is included

The Category B sundial is a rare precisely dated small feature that gives human scale to the nationally important house and designed landscape.

What to notice

  • Multiple incised dial faces set at different angles.
  • The carved coronet, heart and “RR” initials.
  • The simple square plinth supporting the complex dial stone.

Reading the surroundings

The sundial is within private garden ground. Do not enter to inspect it without permission, and never touch, chalk or clean the incised faces.

Timeline

  1. 1714 The dated sundial was made for the Reay household at Tongue House.
  2. 1892 MacGibbon and Ross published the feature in their national survey of Scottish domestic architecture.
  3. 1971 Separate Category B listing recognised the sundial as an individual heritage asset.
  4. 1987 The national landscape inventory recorded it within the terraced garden composition.

What we know — and what remains uncertain

The initials are associated with Reay patronage, but the individual designer or carver has not been identified.
