Keith Marischal is a Scottish Baronial Country house lying in the parish of Humbie, East Lothian, Scotland.

[1] The name Keith is thought to derive from the Brittonic language word */kɛːt/ (related to modern Welsh coed), meaning 'wood'.

Hervey, certainly held the lands at Keith when he erected a Church there at the end of the 12th century obeying a royal decree to that effect.

[5] The house was built as an L-plan tower before 1589 by George Keith, 5th Earl Marischal on the remainder of a previous construction which is heavily obscured, only just discernible in the massive thickness of the southern ground floor internally.

George, 5th Earl Marischal, had stood proxy for King James VI during his marriage to Anne of Denmark in August 1589.

The roof trusses of the tower are reputed to have been made from timber gifted to him by the Danish King Christian IV for services rendered.

Although the coven was reputedly led by Francis Stewart, 1st Earl of Bothwell, one of the leading accused was Agnes Sampson.

The Hope family were engaged in wholesale acquisition of the property of Jacobite sympathisers and eventually managed to amass massive estates in the Lothians over the course of the 18th century.

The ruined chapel that stands in the grounds of the House, across the burn, is a scheduled ancient monument,[9] which is of early Norman Gothic style.

These include a fine early 17th-century monument to the Anderson family, spiro-form carvings on the exterior of the Ogee window of possible Rosicrucian significance, and the unidentified tombstone of a crusading knight.
