to display his collection of modern sculpture, which includes works by Auguste Rodin, Joan Miró, Henri Matisse and Alberto Giacometti. The building is very simple in form, like his early Menil Collection in Houston, Texas, and does not distract from the sculptures within; six walls of travertine marble with a glass ceiling that filters the light define five long galleries, while outside a sunken sculpture garden is placed below the street level, away sheltered from noise giving the appearance of an overgrown archeological excavation. Zentrum Paul Klee (1999–2005) The Zentrum Paul Klee near Bern, Switzerland (1999–2005), continued his series of art museums each very different from the others. It was designed in large part to protect the fragile drawings of Paul Klee from sunlight. It housed in a series galleries resembling rolling hills in the Swiss countryside. Piano explained that the shape of the galleries was inspired by naval architecture and the hulls of ships, which were adapted to the form of waves as his building was adapted to the landscape. High Museum of Art Extension (1999–2005) The original building of the High Museum of Art in Atlanta, Georgia, designed by Richard Meier, and inspired by the form of the Guggenheim Museum in New York City of Frank Lloyd Wright, opened in 1983. Piano's project added four new structures; a pavilion for exhibitions, a gallery for special collections, a building for offices, and a residence hall for the Atlanta College Of Art, creating of additional space. Both the new building and the original building are a gleaming white. A glass bridge with two levels connects the main pavilion with the original part of the museum. The careful management of external light is a particular feature of Piano's buildings; the High Museum Extension rows of curving fan-shaped panels on the facade and on the interior ceiling with filter the sunlight. From the parvis on the outside, the white facade gives the impression that the building has no weight at all. Morgan Library Renovation and Extension (2000–2006) The extension of the Morgan Library in New York City is next to the original library, a monument of Beaux-Arts architecture designed by McKim, Meade and White (1903), which had been expanded several times. Piano extensively renovated the existing structures and a built a new building the same height as the historic building, with a simple rectangular facade that complemented it. He also added a
