Annakūṭa (Annakuta) is a parvata-tīrtha (mountain as a site of pilgrimage). Indra, king of gods, resides on this high mountain located in Mathurā (Mathura).
Vāsudeva Kṛṣṇa (Krishna) once performed a yajña (yajna) in this place, in order to receive blessings from Indra. In order to protect the locality from Indra’s wrath, he held the Govardhana mountain up, in this very place. So the Govardhana mountain is also known as Annakūṭa.
