Clach an Trushal (Scottish Gaelic: Clach an Truiseil, translated to English "Stone of Compassion") is the tallest standing stone (Menhir) in Scotland at 5.8 metres tall. It is sited in the village of Ballantrushal on the west side of Lewis. Like many standing stones, it has been said that it marks the site of a great battle, the last one fought between the feuding clans of the Macaulays and Morrisons - however it is actually the solitary upright stone remaining from a stone circle built about 5,000 years ago. It occupied a place within the circle, although its placement was not central. The second last standing stone was removed in 1914, and used as a lintel.
From the base the stone circle at Steinacleit is clearly visible to the north east. The Callanish standing stones are 20 miles to the south west.
