No recorded prehistoric name for the broch survives. The monument takes its modern name from the surrounding place-name Torwoodlee, preserved in the landscape of the
Scottish Borders near
Galashiels. The first element,
tor, derives from a word used in the
Brittonic languages of early Britain meaning a rocky hill, peak, or prominent outcrop. The element survives widely in British place-names and is typically used to describe hills crowned with exposed rock or rising prominently from the surrounding landscape. The broch and earlier hillfort occupy a raised ridge above the surrounding ground, making the use of this element consistent with the local topography. The remaining elements reflect later Old English place-naming.
Wudu (modern
wood) referred to woodland or forest, while
lēah (modern
lea or
lee) meant a clearing, meadow, or open ground within woodland. The compound name Torwoodlee can therefore be interpreted as "the woodland clearing beside the rocky hill". As with many archaeological monuments in Britain, the Iron Age structure itself was not originally known by this name. Instead, the broch is identified using the later historic place-name attached to the surrounding estate and landscape. The term
broch derives from the
Scots word
brough, meaning a fortified place or stronghold, and is used in archaeology to describe the distinctive drystone tower structures built in northern Scotland during the
Scottish Iron Age. == Description ==
