due to Lalit's effort that the god Rato Machhindranath was settled in Lalitpur. Many believe that the name of the town is kept after his name Lalit and pur meaning township. In May, a chariot festival honoring the deity known as Bunga Dyah Jatra is held in Patan. It is the longest and one of the most important religious celebrations in Patan. During the month-long festival, an image of Rato Machhendanath is placed on a tall chariot and pulled through the city streets in stages. Lalitpur said to have been founded by King Veer Deva in 299 AD, but there is unanimity among scholars that Patan was a well established and developed town since ancient times. Several historical records including many other legends indicate that Patan is the oldest of all the cities of Kathmandu Valley. According to a very old Kirat chronicle, Patan was founded by Kirat rulers long before the Licchavi rulers came into the political scene in Kathmandu Valley. According to that chronicle, the earliest known capital of Kirat rulers was Thankot. Kathmandu, the present capital was most possibly removed from Thankot to Patan after the Kirati King Yalamber came into power sometimes around second century AD. One of the most used and typical Newar names of Lalitpur is Yela. It is said that King Yalamber or Yellung Hang named this city after himself, and ever since this ancient city was known as Yala. In 1768, Lalitpur was annexed to the Gorkha Kingdom by Prithvi Narayan Shah without any battle. Historical monuments The city was initially designed in the shape of the Buddhist Dharma-Chakra (Wheel of Righteousness). The four thurs or mounds on the perimeter of Patan are ascribed around, one at each corner of its cardinal points, which are popularly known as Asoka Stupas. Legend has it that Emperor Asoka (the legendary King of India) visited with his daughter Charumati to Kathmandu in 250 BC and erected five Asoka Stupas, four in the surrounding and one at the middle of the Patan. The size and shape of these stupas seem to breathe their antiquity in a real sense. There are more than 1,200 Buddhist monuments of various shapes and sizes scattered in and around the city. The most important monument of the city is Patan Durbar Square, which has been listed by UNESCO as one of seven Monument Zones that make up the Kathmandu Valley World
