The Perfume Pagoda, known locally as Chua Huong or ‘inner temple’, is at the centre of a very revered and sacred site featuring a maze of mainly Buddhist temples built into the limestone cliffs of Huong Tich. At the heart of this complex lies the Perfume Temple or Perfume Pagoda in the Huong Tich Cave. It is believed that the first temple was built here in the 15th century, although legend declares that the site was actually discovered over 2,000 years ago by a Buddhist monk who was meditating nearby. The mountain foothills are an area of great natural and spiritual beauty filled with streams, tropical plants and temples. There are many pagodas to visit, each offering a different shrine, most of which are Buddhist although one or two are animist. The Perfume Pagoda attracts pilgrims and tourists seeking good luck from the stalagmites and stalactites inside the cave which have been named according to the individual blessing they can bestow. Dun Tien offers prosperity and Nui Co offers the chance of giving birth to a girl whilst Dun Gao translates as a ‘rice stack’ to those hoping for a bountiful harvest. http://www.vietnam-guide.com/hanoi/perfume-pagoda.htm
