I have been experimenting with some new web search engines, alternatives to google: Hakia, Accoona, and Powerset. I think that I liked Hakia the best, but I only did a single search around the term cultural gardens. Hakia produced the most sites directly applicable to my Cleveland Cultural Gardens project; Accoona’s results were less interesting. I have yet to check Powerset.

An international sculpture garden near Arnhem, Netherlands: Kroller-Muller Museum and Sculpture Gardens.
There is a Chinese Cultural Garden in Overfelt Gardens in San Jose: Chinese Cultural Garden.
For a Japanese Garden in Florida: http://www.morikami.org/
For a Shakespeare Garden in Montgomery, Alabama: Welcome to the Blount Cultural Park.

And, now some links for me to add or check on the Cultural Gardens site; for the Indian community: http://www.fica-cleveland.org/ and for the Association of African-American Cultural Gardens.
