As you enter Durbar Sq through the western gate, look left to a gateway flanked by two stocky stone lions, erected by King Bhupatindra Malla in 1701. On either side are statues of the terrible Bhairab (right), the rending, sundering incarnation of Shiva, and his consort on the left side, the equally terrible Ugrachandi (Durga). It is said that the unfortunate sculptor had his hands cut off afterwards, to prevent him from duplicating his masterpieces.
Ugrachandi has 18 arms holding various Tantric weapons symbolising the multiple aspects of her character. She is depicted casually killing a demon with a trident to symbolise the victory of wisdom over ignorance. Bhairab gets by with just 12 arms, one holding two heads impaled on a trident and another holding a cup made from a human skull. The statues originally guarded a courtyard that was destroyed in the 1934 quake.
