The Arizona Capitol building is now turned into a historical museum. The admission is free and parking is free in the lot across the street. It has 4 floors of the history of Arizona and lots of interesting facts about the state itself. It just so happens the time I visited the place, there was a 50 years exhibit about my favorite basketball team, the Phoenix Suns! So glad they had this, I was able to read about all the rich history of a great NBA franchise I grew up loving. The people working there were very nice and treated us really well and were very helpful. Great free attraction in the city of Phoenix!
