A hiti is a traditional Newari step-well and water spout — a sunken stone basin fed by underground springs, with carved stone spigots from which water flows continuously. The Thanthu Darbar Hiti, near Durbar Square, is one of Bhaktapur's better preserved examples: an open paved area with a stepped descent to the water level, carved stone nozzles in the shape of makara (mythological sea creatures), and stone guardian figures.
The hiti were the public water supply for medieval Bhaktapur, and they still function — water flows from the spouts year round, and local people use them for washing. Watching the morning activity at a hiti gives a good sense of the continuity between Bhaktapur's medieval infrastructure and its present daily life.
