Which great architectural attractions have you visited?
The "Sundial Bridge at Turtle Bay" in Redding, CA by Santiago Calatrava is one of the most unique and surprising great architectural attractions I have ever seen.
This bridge is such a surprising structure to find in Redding, CA because the bridge is an example of the height of design and engineering, where Redding is a town whose time is more of the mid-twentieth century in both culture and design.
I like many of Dubai's architectures.
The second one is Dubai performing arts centers, designed by Zaha Hadid, and its 3d rendering drawn by Frontop.
I have heard that Dubai is an architectural dreamscape.
