A rare example of well-preserved traditional Vietnamese architecture, the Temple of Literature honors Vietnam’s finest scholars. Founded in 1070 by Emperor Ly Thanh Tong, the attractive complex is dedicated to Confucius (Khong Tu) and was the site of Vietnam’s first university (1076). The altars are popular with students praying for good grades; while the pagodas, ponds and gardens of the five courtyards make picturesque backdrops for student graduation photos. It is depicted on the 100,000d note. Gifted students from all over the nation headed to Hanoi to study the principles of Confucianism, literature and poetry. In 1484 Emperor Ly Thanh Tong ordered that stelae be erected to record the names, places of birth and achievements of exceptional scholars: 82 of 116 stelae remain standing, mostly atop turtle statues.
