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 and reached by a red bridge which named is The Huc, 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.
In the middle of the lake is another small island, called Turtle Tower - a special and long-standing symbol of Hoan Kiem Lake.
