Used a backdrop for weddings, the Loretto Chapel is one of Santa Fe's oldest and most dear attractions. Formerly a Roman Catholic church, it now serves as a museum and wedding venue. Perhaps beyond its grand beauty and elegance, Loretto Chapel's continued allure lies in its mysterious spiral staircase. Both the identity of its builder and the stunning physics of its construction - there were no supports holding it as it spirals into the choir loft - remain a mystery. Legend says that St. Joseph himself made it, as the man who did build the staircase disappeared before the nuns were able to pay him, and the wood used was not native to the area. It is a stunning salute to the science of physics and the hearts of believers.

Collect a free self-walk brochure from the Visitor Information Centre and discover magnificently restored buildings built by the first settlers, and the best collection of Art Deco architecture in Queensland. Many buildings are recognised for their national importance and listed with the National Trust. The walk begins in River Street opposite Carlyle Street, and takes approximately 90 minutes.

The Roman amphitheatre of Cartagena in Murcia, which was built between 5 and 1 BC, is wonderfully preserved, and the museum close by offers excellent exhibits that display interesting historical artefacts.
