Nansha Tin Hau Palace is a mazu temple on the southeastern slope of the Dajiao Mountain

Facing the Lingdingyang (Lingding Ocean), the mouth of the Pearl River, Nansha Tin Hau Palace is a mazu temple on the southeastern slope of the Dajiao Mountain in Guangzhou City and covers about 100 hectares (247.1 acres). The architecture combines both the style of the Forbidden City in Beijing and the sublimity of Dr. Sun Yat-sen's Mausoleum in Nanjing. It is the largest palace compound of its category in the world. It is reputed as the 'First Tin Hau Palace under Heaven' and the biggest Mazu Temple in southeastern Asia. The canton fair 2013 will be helded in Guangzhou, maybe you can go to Nansha Tian Hou Palace if you have a time.

It was built to worship the Goddess of sea, also called Mazu (or Tianhou in Chinese, literally meaning Heavenly Empress) by the people, whose real name is Linmo (960-987). There are many touching stories about her helping people in shipwrecks, so she was thought to be the incarnation of the goddess of sea and was paid homage by over 100 million believers in more than twenty countries.
This palace was first built in the Ming Dynasty, then was renovated during the reign of Emperor Qianlong (1737-1795) in the Qing Dynasty (1644-1911), but was later ruined. The one we see now was rebuilt in 1994 and completed in 1996.
When you arrive there, you will first reach the Tin Hau Square which covers an area of 1.5 hectares (about 3.7 acres). At the center of the square stands a huge statue of the Goddess. The statue faces the Lingdingyang and is about 14.5 meters (about 47.6 feet) high, made of 365 pieces of granite. It symbolizes that mazu could bless fishermen and bring favorable weather for the whole year.
Mazu , also spelt Matsu, is the indigenous goddess of the sea who is said to protect fishermen and sailors, and is invoked as the patron deity of all Southern Chinese and East Asian persons. Born as Lin Moniang  in Fujian around 960 CE, worship of Mazu began around the Ming Dynasty, when many Taoist temples dedicated to her were erected all across Mainland China, later spreading to other countries with Southern Chinese inhabitants.
