Texas State Capitol is one of America's most well-known state capitols. From architectural point of view it's an amazing building to see. The Renaissance Revival style Capitol was built already in 1888 based on the architecture of 15th-century Italy. The center of the capitol under the dome is open all the way down, and it is a gorgeous space to see. In all honesty, it is best toured on a hot Texas day to take a break from the heat.
