The temple of Tankeshwor Mahadev lies at the bank of Bagmati River near Kalimati in Kathmandu. It houses one of the sixty-four famous Shivalingas of Nepal.

The temple is not built in the traditional pagoda style but seems to use Indian influences. It is believed that the Ranas brought the Shivalinga from India to Kathmandu and established an Indian style temple to house it.

As it lies in the heart of the city, devotees visit the temple and offer holy water of Bagmati to the deity all through the year, especially on Mondays.
