Deosil Gate
The Deosil Gate is a gate in the city wall of Ankh leading from the King's Way and its extension, King's Down, and to the road to Quirm. Deosil is an old word for "sunwise" or "clockwise" (see also the annotation to Widdershins.) Unlike the Hubwards Gate, it is almost exactly on its named direction.
The gate collapsed during the events of The Colour of Magic and was presumably rebuilt later.
