The temple is in the middle of rectangular courtyard with rest houses around. There is a column with peacock on the top just in front of the temple. The peacocks can also seen in the corners of the temple. There is also a Bhairab temple on premise. Local people from the Newar community performs several ceremonial rituals everyday. The temple is crowded during the Balkumari Jatra, which is a part of Bisket Jatra in mid April. During the festival, locals gather and take out a procession carrying 32 chariots containing the idols of different gods and goddesses. People smear each other with Vermilion powder and sing and dance to the tune of traditional music during the procession.

The princess became pregnant, she asked the merchant to take her with him. The merchant agreed in one condition that she should bring the goddess Balkumari along with her.
