Blending into the surrounding red rocks, this chapel was built in 1956 by visionary architect and sculptor Marguerite Brunswig Staude. It was designed to reflect the spiritual essence of the Sedona landscape.

The striking design is rounded off with a 210-foot-tall (64m) central nave and windowed altar.

Self-guided tours are available to those who want to discover its grand hallways, marble staircases and ceremonial and legislative offices.

Built in 1910 to replace the earlier capitol building – which is still standing in downtown Frankfort and now serves as a museum – the new capitol is actually the fourth capitol building since Kentucky achieved statehood in 1792.

Somewhat reminiscent of a Cinderella castle, this dreamy cathedral is one of America's most famous places of worship. Finished in 1727 and brought to life by French engineer Adrien De Pauger, the original cathedral sadly burnt to the ground less than 60 years later. Its replacement took shape in 1794 and has been standing at the heart of New Orleans since then.

If you'd like to visit, note that the church is closed during winter.

Another beautiful example of Neoclassical architecture in America, this church was designed by the same architect who conceived the United States Capitol in Washington DC.

Since then, the cathedral has even hosted Pope John Paul II.

This historic 17th-century mansion in Salem was made famous by Nathaniel Hawthorne's novel of the same name, published in 1851.

Today, it's a popular tourist attraction and is even said to be haunted.

An Art Deco masterpiece, this 1920s building perfectly summarises the golden age of Detroit. The exterior is made of Indiana limestone and features carvings, friezes and sculptures that evoke the spirit of Detroit's historic industries – automotive and manufacturing.

Looming over Minnesota's capital is the Cathedral of Saint Paul and its two soaring towers.

If you take a tour, you'll see that the Senate chamber is adorned with paintings of Wyoming's early pioneers and other famous figures.
