Ho Tay is the largest of all the lakes in Ha Noi. The lake is on the northwest part of the city. Long ago, the lake was a branch of the Red river but later, as the river changed course, the lake remained a body of water just west of the river. There are many legends associated with West Lake. The most popular is the

legend of the golden buffalo.

As the story goes, there once was a medicine man who was a giant. He is well known in Vietnam for his medicine practice and the king often used him to treat the royal family. His fame reached China and he was invited to China to treat the king. He was successful where others have failed so the king was going to reward him with great wealth. He refused offerings of gold and only requested that the king give him all the black copper in the king's vault. The king agreed and the giant left for Vietnam with vast amounts of black copper. In Vietnam the giant molded a giant bell of black copper. The giant rang the bell and the sound resonated all the way to China. In the king's vault there was a golden buffalo. Upon hearing the sound of the bell, the buffalo came to life (because he thought that his mother was calling him) and charged southward. Upon reaching Ha Noi, the buffalo trampled the land in the area near Red river. Over the years, this area filled with water and became Ho Tay or West Lake.

Ho Tay has always been an area for vacationing royalties. When Ha Noi was still the capital city, the kings from the Ly and Tran dynasty built summer homes along the lake. In the north end of the lake there are several villages famous for their flowers and fruits plantations. Most famous is Nghi Tam village, the birth place of Ba Huyen Thanh Quan, one of Vietnam's premier Poetess.
