Hoa Lu is the legendary ancient capital of Vietnam. The old capital was built more than 10 centuries ago under the reign of the Dinh Dynasty and Le Dynasty. It was the nation's capital for 41 years (968-1009). The capital then was moved to Thang Long under the Ly Dynasty in 1010. With the size of 3,000ha, Hoa Lu is protected by a natural wall with surrounding Trang An limestone mountains and Hoang Long river. The combination between mountains and rivers make Hoa Lu surroundings very picturesque. Hoa Lu is famous for the number of palaces, pagodas, tombs and pavilions that were built by different dynasties. Bao Thien Tue Palace that was plated with gold and silver is very popular with its architecture. There were also two famous temples that were built in the 11th century to dedicate King Dinh Tien Hoang and his successor Le Dai Hanh.
