Kasthamandap (In sanskrit, Kastha= wooden, Mandap= Pavillion) is locally known as Maru Satal is a huge wooden pavilion having 64-feet tall superstructure dedicated to Guru Gorakhnath- (Sanskrit for Gau+Raksha+Nath: Cow+Protect+Lord, ie, The Lord who protects cows) - a form of the god Shiva. The Kastha Mandap was built from the wood of this single tree; and the name Kathmandu was derived from this Kastha Mandap. Three-storey Kastha Mandap has an open ground floor, underlining its original purpose as a public building. Legend has it that Saint Gorakhnath attended the chariot procession of Machindranath in human disguise. Unfortunately, he was recognized by a tantric who cast a spell on him, imprisoning him for eternity in the Kathmandu valley. Desperate to free himself from imprisonment, Gorakhnath made a deal with the tantric who needed sufficient materials for building a wooden temple. A giant Sal tree grew in his land which he (tantric) used to construct the temple of Kasthamandap to dedicate to Gorakhnath. An historic account of 1107 AD mentions the existence of the temple of Kasthamandap in its current location. However many Lichchhavi inscriptions name religious buildings as mandaps during their reign which could very well make Kasthamandap, a product of the Lichchhavis dated back to 7th century.. It was extended under the reign of King Laxmi Narsingha Malla (1620 - 1641, r 21 years) and an interesting legend is attached to its wooden construction. The saying goes in Kathmandu that the temples were for the gods, palaces were for kings, and the satal (rest house) was for ordinary people. And although the valley has many satal, Kasthamandap was the biggest of its kind and it was then on the historic trans-Himalayan trade route between India and Tibet, and Kasthamandap was the bustling rest house where buyers and sellers from the north and south mingled. The exchanges were not just of goods and commodities, but were also cultural and religious. It is also colloquially called Maru Satha (empty rest house). Everything happened around Kasthamandap, in the bustling Maru bazaar that exists to this day. At the four corners is an image of four statues of Ganesh representing four Ganesh of the Valley, Surya Vinayak, Chandra Vinayak, Jal Vinayak and Karya Vinayak (or Ashok Vinayak). To this day, the temple has stood steadily without the use of any metal nails or rivets.
