Immediately below the light room of Scotland’s Bell Rock lighthouse was a library. Writer R.M. Ballantyne spent two weeks there in 1865:

[I]t is a most comfortable and elegant apartment. The other rooms of the lighthouse, although thoroughly substantial in their furniture and fittings, are quite plain and devoid of ornament, but the library, or ‘stranger’s room’, as it is sometimes called, being the guest-chamber, is fitted up in a style worthy of a lady’s boudoir, with a Turkey carpet, handsome chairs, and an elaborately carved oak table, supported appropriately by a centre stem of three twining dolphins. The dome of the ceiling is painted to represent stucco panelling, and the partition which cuts off the small segment of this circular room that is devoted to passage and staircase, is of panelled oak. The thickness of this partition is just sufficient to contain the bookcase; also a cleverly contrived bedstead, which can be folded up during the day out of sight. There is also a small cupboard of oak, which serves the double purpose of affording shelf accommodation and concealing the iron smoke-pipe which rises from the kitchen, and, passing through the several storeys, projects a few feet above the lantern. The centre window is ornamented with marble sides and top, and above it stands a marble bust of Robert Stevenson, the engineer of the building, with a marble slab below bearing testimony to the skill and energy with which he had planned and executed the work.

Stevenson, perhaps fittingly, was the grandfather of Robert Louis Stevenson.
