The '''Bonnington Pavilion''' or '''Hall of Mirrors''', now a ruin, overlooks the Corra Linn falls on the River Clyde. Alternative names are the Corra Linn Pavilion and the Falls of Clyde summerhouse. The name comes from the Gaelic 'currach', a marshy place. A legend gives 'Cora' as a daughter of Malcolm II of Scotland, who leapt to her death here whilst trying to escape imagined danger.

The building is dated 1708 over the entrance and was constructed by Sir James Carmichael of Bonnington House for the entertainment of his friends and guests. The building had mirrors installed which gave a view of the Falls of Clyde. A painting of Corra Linn in 1800 gives some idea of the magnificent view that visitors would have seen in the 18th-century when the Clyde's waters had a much greater flow. At the time of the construction of the pavilion it was generally felt by the aristocracy that nature was cruel and ugly and that women of good breeding should not look upon it unless it was reflected in a mirror or seen through a frame, thereby detaching the view from the aspect of harsh reality and transferring it to that of good taste and high art.

The building was still in use in the early 19th century, although a Mr. Stoddart refers to it as  a summerhouse. Mr.Garnett on his 1800 Scottish tour states that ''.. as at Dunkeld, mirrors are placed, by the reflection of which we had different views of the water.''  It is not clear when the building was abandoned.

The pavilion had 2 floors, and the bottom floor may have been used at one stage as a kitchen for the preparation of refreshments for the ladies and gentlemen who came down from Bonnington House to view the falls. A relatively large window, probably originally having shutters either side, looks onto the falls. The entrance door has a window set on each side. A window and ground floor door were present in each of the two side walls of the building; providing up to three doors altogether into the ground floor and a total of five windows. A sketch from 1837 shows a different arrangement of the steps leading up to the door and a stone gable end, with highly ornate 'crow step' ornamentation, which would have given the building a typical arched sloping roof. It may well be that the changes to the entrance steps took place when the hydroelectric power station was constructed in 1926 as the pipes carrying the water to the turbine house run very close to the pavilion entrance and they had to be moved to run parallel to the front of the building.

The building shows signs of other alterations, such as the closing up of one of the lower ground front 'servants' entrance to the suggested kitchen area and the provision of a balustrade at the viewing window. Some modern repairs have been carried out to stabilise the building as indicated by recent pointing work, new wood lintels, etc.

As stated, the pavilion had mirrors which reflected the falls, giving visitors, who sat with their backs to the window, the illusion, once the shutters or 'doors' were thrown open, that they were standing in the middle of the waterfalls. The author Swan records that ''A beautiful though more distant view of this extraordinary scene, may be had from the window of a pavilion, erected by Sir James Carmichael of Bonniton, placed far above, on the very summit of the sloping bank which rises from the perpendicular rocks, can contemplate the whole freed from those feelings of terror with which in nearer situations, he cannot fail to be visited. Indeed, the scene has here more of the effect of a picture, or a beautiful panoramic view; the trees through which it is seen adding their interest to the foreground, or forming as it were a framework at the sides. At the opposite end of the pavilion, a Mirror is placed, in which this rich landscape is reflected; and from its position, the spectator is almost led to believe that the cataract is tumbling upon his head.''

J. M. W. Turner, Sir Walter Scott, Samuel Taylor Coleridge and his friend William Wordsworth all visited. Turner produced a painting of the falls and Wordworth immortalised Corra Linn in verse in 1802.

The Oxford educated cleric Rev. William Gilpin (1724–1804), a schoolmaster in Surrey, toured Britain  and visited the Falls of Clyde. He built an enormously influential theory on this convergence of travel and artistic recreation. John Stoddart relates that when he visited in 1800 the mansion house of Bonnyton (Bonnington) was the seat of Lady Ross. He commends her for permitting unrestricted access to the falls and states that a porter was based at the Bonnyton Lodge house who would escorted visitor to the best viewing points and to the 'summer-house' as he calls it.
