Hoan Kiem Lake
Hanoi's most well-known landmark is tranquil Hoan Kiem Lake, nestled just on the southern edge of the old town quarter. The major tourist attraction upon the lake is the small island (reached by a red bridge) that holds Ngoc Son Temple, dedicated to three grand figures from Vietnamese history: La To (revered as a patron saint of physicians); the renowned scholar Van Xuong; and the 13th-century general Tran Hung Dao, who fought against the invading Mongol army.
Another tiny island on the southern section of the lake holds the stocky Turtle Tower - best viewed from the bridge.
