Amongst the temples in Jammu, the Raghunath Temple takes pride of place being situated right in the heart of the city. This temple is situated at the city centre and was built in 1857. Work on the temple was started by Maharaja Gulab Singh, founder of the Kingdom of Jammu and Kashmir, in 1835 AD and was completed by his son Maharaja Ranbir Singh in 1860 AD. The inner walls of the main temple are covered with gold sheet on three sides. There are many galleries with lakhs of saligrams. The surrounding Temples are dedicated to various Gods and Goddesses connected with the epic Ramayana. This temple consists of seven shrines, each with a tower of its own. It is the largest temple complex in northern India. Though 130 years old, the complex is remarkable for sacred scriptures, one of the richest collections of ancient texts and manuscripts in its library. Its arches, surface and niches are undoubtedly influenced by Mughal architecture while the interiors of the temple are plated with gold. The main sanctuary is dedicated to Lord Vishnu's eighth incarnation and Dogras' patron deity, the Rama. It also houses a Sanskrit Library containing rare Sanskrit manuscripts.
Situated at an altitude of 5,200 feet above sea level, the Holy Cave Shrine of Mata Vaishno Devi or Trikuta Bhagwati has been a beacon of faith and fulfilment to millions of devotees from all over the world. The pilgrimage to the Shrine holds great significance for the pilgrims. The Yatris have to undertake a trek of nearly 12 km from the base camp at Katra. At the culmination of their pilgrimage, the yatries are blessed with the Darshans of the Mother Goddess inside the Sanctum Sanctorum - the Holy Cave. These Darshans are in the shape of three natural rock formations called the Pindies. There are no statues or idols inside the Cave.
A geological study of the Holy Cave has indicated its age to be nearly a million years. As per belief the practice of worshipping Shakti, largely started in the Puranic period and the first mention of the Mother Goddess is in the epic Mahabharat. When the armies of Pandavs and Kaurvas were arrayed in the battlefield of Kurukshetra, Arjun, the chief warrior of Pandavs upon advice of Sri Krishna; meditated upon the Mother Goddess and sought Her blessings for victory. This is when Arjun addresses the Mother Goddess as 'Jambookatak Chityaishu Nityam Sannihitalaye', which means 'you who always dwell in the temple on the slope of the mountain in Jamboo' (probably referring to the present day Jammu). On a mountain, just adjacent to the Trikuta Mountain and overlooking the Holy Cave are five stone structures, which are believed to be the rock symbols of the five Pandavs.
