A new building for The California Academy of Sciencies, which is the official name for San Franciso's aquarium and planetarium, is currently being built in Golden Gate Park across from the DeYoung Museum, and it is going to be amazing.
I walk through the park a lot, and I've passed the bulding in various stages of construction, and it's very impressive. It preserves some of the exterior of the old building, but then has huge spaces constructed of glass. The roof is going to be a "living" roof, filled with plants. The building is scheduled to open in the Fall of 2008.
In the meantime, some of the fish and reptiles and penguins have been trucked downtown to a temporary museum at 874 Howard Street. This is a wonderful little museum, which in addition to traditional small tanks, has one based on a coral reef that is three stories high. The temporary museum will be closing down on January 7, 2008, though, so that they can start moving the animals back to their new home in the park. It's going to be a big job!
When I was at the temporary museum, I saw a presentation about the new musuem. I am convinced that this will be one of the best acquariums/science museums in the world, as well as a top tourist attraction for San Francisco. So if you are going to be here in the Fall of 2008 or later, don't miss it! I'm very excited already.
You can get a lot more information and keep track of the progress of construction on the Museum's website at http://www.calacademy.org/
