Chu Van An High School is one of the oldest and most prestigious state schools in Viet Nam. Established in 1908 by the French, the school was located beside the West Lake, and was originally named after the location it was in. It is a very pleasant, spacious school with great views of the lake from the classroom windows. In 1943, the school was moved to Ninh Binh, and was not moved back to Ha Noi until 1945. In that year, the school was renamed Chu Van An after a famous Vietnamese Confucianism teacher of the Tran Dynasty. Professor Nguyen Gia Tuong became the first Vietnamese principal of the school. Many famous people like ex-Prime Minister Pham Van Dong, Doctor Ton That Tung and poet Xuan Dieu used to be the school's students.
Today the school is still located in the same area, and has maintained its prestige, as well as its reputation as one of the top schools in Ha Noi. It is very difficult to be admitted to the school.
