Pittarthie Castle is the remains of what was a laird’s tower house in Fife, Scotland dating to the end of the sixteenth century.

[1][3] The building is a defensible house that was built in a staggered "L" plan with a stair tower is located in the inner angle.

The stonework is good quality rubble with ashlar dressings, but much coarser masonry appears at the bottom of the south wall and is possibly evidence of an earlier building.

The building's defences include a gunloop beside the roll-moulded door and pistol holes below all the window sills.

[2] The date 1682 is carved, together with William Bruce's arms and initials, on a segmental pediment over the first floor hall's south window.

In the tunnel-vaulted jamb, there is a kitchen with a huge north fireplace, and a water inlet in the west wall.
