Yes, you can still see re-created thatched-roof huts from ancient Hawaii. However, they won't be on the street but in Honolulu's Bishop Museum or at the Polynesian Cultural Center. You also can get a great feel of what life was like in the 19th century for the American missionaries who ventured to this "heathen" land by visiting the Mission Houses Museum. Turn of the 20th century architecture can still be observed in downtown Honolulu.
The art scene in Honolulu is more vibrant than ever, especially with the Hawaii State Art Museum (housed in the original Royal Hawaiian Hotel, built in 1872, during the time of King Kamehameha V), filled with works created by artists living in Hawaii; the Honolulu Academy of Arts, the state's only general fine arts museum, with an excellent collection of Asian arts; and the Contemporary Museum, three acres of sculptured gardens and displays of contemporary art in the museum.
