In 1768, in the southeast part of the palace, four lookout towers were added by Prithvi Narayan Shah.
The stone is a jaladroni (drinking fountain) and legend states that for someone who understands all 15 languages, milk instead of water would spring from it.
While the courtyard was built during Malla Period, the buildings around it, which depict intricately carved doorways, windows, and struts, were creations of the Rana rulers.
[3] Mul Chok, dedicated to Taleju Bhawani, is a courtyard with two storey buildings all round that are exclusive places for religious rites.
Taleju Temple with a golden torana (door garland) is located to the south side of the courtyard.
At the center of the courtyard, there is a golden waterspout, known as Sun Dhara, said to be spring sourced from Budhanilkantha, in the north part of Valley.
It is an ornately carved spout sunk several metres below the courtyard level and the Malla kings used it for their daily ablutions.
[3] On the west side of Nasal Chok, the Tribhuwan Museum has exhibits of items of the grandfather of King Birendra.
The palace gets its name from the stone image of Hanuman, the Hindu monkey god, that sits near the main entryway.
