San Antonio's main library, opened in the mid-1990s at a cost of $38 million, has a number of important holdings (including part of the Hertzberg Circus Collection, scattered when it lost its museum home in 2001), but it is most notable for its architecture. Ricardo Legorreta, renowned for his buildings throughout Mexico, created a wildly colorful and whimsical public space that people apparently love to enter -- by the second month after the library opened, circulation had gone up 95%. The boxy building, painted what has been called "enchilada red," is designed like a hacienda around an internal courtyard. A variety of skylights, windows, and wall colors (including bright purples and yellows) afford a different perspective from each of the six floors. A gallery offers monthly exhibits of paintings, photography, textiles, and more.
