Madayi Kavu, Hindu temple in Kannur district, India

Madayi Kavu, also called Thiruvarkadu Bhagavathy Temple, is a Bhadrakali shrine at Madayi in Payangadi, Kannur district. Its central shrine has a sloped red-tiled roof, a carved triangular gable with two painted wooden brackets, and a facade on red-painted pillars. A dark doorway is flanked by a "DASOOTHI COUNTER" sign and a blue "Vazhipadu Counter" sign, with a red-tiled path leading in.

Regional sources identify this site as the second shrine for Bhadrakali in Kerala, following the older temple in Kodungallur. For centuries, the place remained closely tied to the ruling family of Chirakkal, who honored their personal guardian deity here.

The goddess is invoked as Tiruvarkkad Achchi, and the shrine is held to be the mother temple of North Malabar's Bhadrakali shrines. The main offering is vazhiyaradi puja; cooked chicken and green gram are presented as niwedya in the Koula tradition, a practice rare elsewhere. During smallpox outbreaks, devotees used to offer black pepper to Madayikkavilamma.

The temple is in Eripuram on the Payyanur route via Pazhayangadi, with the nearest railway station at Pazhayangadi on the Mangalore–Palakkad line. Men may wear a mundu; shirts, lungis and banians are not allowed in the sanctum, and jeans are barred for women. On ordinary days the gate opens from 4:30 am to noon and 5 to 7:30 pm, and on some months and on Tuesdays and Fridays from 2 am.

The temple keeps no night-time athazha puja: at about 8.30 pm the offering is placed inside the sanctum, and the belief is that the deities themselves come to worship the goddess. Next morning the priest opens the door, takes the goddess's sword and sets it at the north-west corner of the namaskara mandapam before the offering is removed.
