This temple dedicated to Lord Shiva, is distinctive with its white towers, welcoming at the entrance.  Small and exquisite, it stands on atop a small hill, surrounded with lush greenery, this temple creates a separate place in the hearts of the onlookers.  This place is 22 kms from Panaji and 26 kms from Margao at Priol-Ponda Taluka.  This temple is one of the largest, wealthiest and most frequently visited temples in Goa. 

History
This temple actually had its origins in Kushasthali, now know as Cortalim, a village in Salcete. Salcete fell into Portuguese rule in 1543. This temple was dutifully preserved until the arrival of the Inquisition from Europe in 1567, when it was vandalised and demolished . In the year 1560, the Portuguese started Christian conversions in Salsette taluka, the Saraswats of Vatsa Gotra felt insecure and shifted the Mangesh Linga from the original site at the Kushasthali or Cortalim on the banks of river Aghanashini to present place in May 1st, 1560 A.D. (according to Hindu calendar - 1482 sakha) to the locality now known as Mangeshim in Priol village of Atrunja Taluka, which at that time was ruled by the Hindu kings of Sonde. After remaining in the house of a temple priest for sometime, Sri Mangesh deity was finally installed in its present site at Priol. The original site was a very simple structure, and the current structure was only built under Maratha rule, some 150 years after it had been moved. The Peshwas donated the village of Mangeshi to the temple in 1739 on the suggestion of their Sardar, Shri Ramchandra Malhar Sukhtankar, who was a staunt follower of Shri Mangesh. Ironically, just a few years after it was built, this area too fell into Portuguese hand in 1764, but by now, the Portuguese had lost their initial religious zeal and had become quite tolerant of other religions, and so, this structure remained untouched.

Legends
The Mangesh Linga is said to have been consecrated on the mountain of Mangireesh (Mongir) on the banks of river Bhagirathi by Lord Brahma himself, from where the Saraswat Brahmins brought it to Trihotrapuri in Bihar. They carried the linga on to Gomantaka and settled at Mathagrama, the present-day Madgoa, establishing their most sacred and ancient temple of Mangesh on the banks of the river Gomati or Zuari as it is called today. Lord Mangesh is worshipped here in the shape of a Shiva linga. According to the legends Lord Shiva had manifested in to a tiger to scare Parvati. Paravati who was paranoid at the sight of the tiger went in search of Lord Shiva. Parvati was supposed to say "Trahiman Gireesh" but instead out of nervousness she said: "Trahimangeesh"

Description of the Temple
There is a prominent Nandi Bull which is considered to be the Vahana (Vehicle) of Shiva. The temple complex consists of a spacious courtyard surrounded by the temple itself and rooms for weddings and pilgrims. The temple also has a magnificent water tank, which is believe to be the oldest part of the temple. The Sabha Griha is a spacious hall which accomodates over 500. The decor includes the chandeliers of the nineteenth century. There are photos of Lord in different styles. The devotees are said to assemble here twice a day to meditate and seek peace, solace and the blessings of the Lord. This room also facilitates instrumental equipments to listen to Hari Katha and kirthana after which the devotees have their first glimpse at the Lord. The central part of the Sabha Griha leads to the Garbha Griha which is kept clear at all times. This allows the devotee to have the darshan of the Lord even from the entrance. The image of Mangesh resides in the garbhgriha of the beautiful temple.
