The Lincoln Memorial Reflecting Pool was designed by Henry Bacon, constructed in 1922-1923, following the dedication of the Lincoln Memorial. It is approximately 2,030 feet (620 m) long and 167 feet (51 m) wide. It has a depth of approximately 18 in (46 cm) on the sides and 30 in (76 cm) in the center. It holds approximately 6,750,000 US gallons (25,600,000 liters) of water.
Part of the iconic image of Washington, the reflecting pool hosts many of the 24 million visitors a year who visit the National Mall. It is lined by walking paths and shade trees on both sides. Depending on the viewer's vantage point, it dramatically reflects the Washington Monument, the Lincoln Memorial, the Mall's trees, and/or the expansive sky.
