The Chinese artist and political dissident Ai Weiwei was one of the most famous prisoners in recent history. Now he’s taking on one of the most infamous prisons of all time, using Alcatraz as the inspiration and site for a series of new artworks to debut next September.

U.S. Secretary of the Interior Sally Jewell outlined a major push Thursday to inspire children and teenagers to enjoy the outdoors and chose to announce the campaign at Crissy Field because the nearly 80,000-acre Golden Gate National Recreation Area is the nation's youth programs leader

This week, park-loving San Franciscans should be turning out in force when the board of the Presidio Trust meets to hear public comments on the three development proposals in play for Crissy Field.

Conservation Corps North Bay’s Environmental Stewardship Award Honors Golden Gate National Parks Conservancy President & CEO Greg Moore

San Francisco’s Golden Gate National Parks Conservancy just landed the largest cash gift ever given to a national park — putting it halfway towards the money it needs to transform the Presidio.

The largest cash gift in national parks history is intended to be the catalyst to create 10 acres of parkland connecting the heart of the Presidio to Crissy Field and the bay.

Ten years ago, the Garden Conservancy, whose mission is to preserve exceptional American gardens, in partnership with the Golden Gate National Parks Conservancy and the National Park Service, decided to restore the Alcatraz gardens after decades of neglect.

Abandoned after the prison closed in the early 1960s, the Gardens of Alcatraz are a study in survival.

Three finalists are vying for the coveted site of the current Sports Basement in the Presidio. The proposals being presented for discussion are the Lucas Cultural Arts Museum, the Presidio Exchange and the Bridge/Sustainability Institute. The Presidio is a national park site.

The Presidio Trust has a spectacular opportunity to remake two sections of the Presidio with amazing views of San Francisco Bay and the Golden Gate Bridge. The process to select a project will redevelop the former commissary building, which currently houses the Sports Basement sporting goods store.

Three very different proposals were presented Monday for one of the most potentially memorable sites in San Francisco - 8 acres facing the marsh at Crissy Field, downhill from the Presidio's Main Post.
