Beneath Houston's downtown skyline, the parklands of Discovery Green are filled with striking public art. While nearby, the Museum District is home to 18 cultural, historic, and science museums, all within walking distance of one another. Here you'll find one of the world's great private art collections. The Menil Collection showcases treasures from antiquity through to the works of modern masters like Picasso, Warhol, and Rothko. Displayed simply within this Renzo Piano-designed gallery, the collection prides itself on being accessible, friendly and free. Nearby, continue your journey through the artistic ages at the Museum of Fine Arts. While just a few blocks away at the Houston Zoo, come face to face with some of Planet Earth's living treasures. Still within the Museum District is historic Hermann Park, home to the soaring Pioneer Memorial and the Reflecting Pool. If Hermann Park is the place Houstonians go to relax, Memorial Park is the place they go to get active, and back to nature. Set within the park is the Houston Arboretum and Nature Center, over 150 acres of tranquil forest, meadow, and wetlands habitats. Flowing gently through the heart of Houston is Buffalo Bayou. At its mouth rises the San Jacinto Memorial, marking the site where in just 18 minutes, General Sam Houston's army won the Lone Star State its independence.
